My Brain Won’t Stop Asking Unanswerable Questions: Dealing with Existential Anxiety.
What if there is no meaning to life? What happens after we die? How do I know reality is real? What if I never figure it out? What if everything I believe is wrong?
Questions about death, consciousness, existence, free will, reality, and the meaning of life are part of being human. For some people, exploring these questions is interesting, philosophical, or even enjoyable. For others, they can become a significant source of anxiety.
Instead of wondering about a question and eventually moving on, you might feel an urgent need to figure it out. You may spend hours researching different explanations, reading about philosophy or science, asking other people what they believe, or mentally debating every possible answer.
The hope is usually that one more explanation will finally provide enough certainty to put the question to rest. Unfortunately, when you are trying to find a definitive answer to something that may be inherently uncertain, that sense of certainty can remain just out of reach.
What is existential anxiety?
Existential anxiety refers to fear or distress related to fundamental questions about existence and the human experience. It can centre around concerns such as:
What happens after death?
What is the meaning or purpose of life?
What if life has no meaning?
Why am I here?
What if I waste my life?
How do I know reality is real?
How do I know other people experience consciousness?
What if everything is predetermined?
What if I make the wrong choices with my life?
What if there is nothing after death?
What if there is something after death?
How can I know that what I believe about the world is correct?
There is nothing inherently unhealthy about thinking about these topics. Humans have wrestled with many of these questions for thousands of years.
The difficulty arises when uncertainty itself begins to feel intolerable and your mind starts treating an existential question as a problem that needs to be solved before you can feel okay again.
“I just want an answer”
This is one of the most frustrating parts of existential anxiety. It can genuinely feel as though finding the right answer would make the anxiety disappear.
You might read an article, watch a video, research different philosophical perspectives, ask someone what they believe, or spend a long time working through the possibilities in your head. Sometimes you find an explanation that feels reassuring.
Then another question appears: But how do I know that's actually true?
The relief disappears, and the search begins again.
Over time, this can create a cycle of question → anxiety → researching or analyzing → temporary relief → doubt → more researching or analyzing.
At that point, the problem may no longer be the existential question itself. The problem may be the relationship you have developed with uncertainty around the question.
Why trying harder to “figure it out” can make anxiety worse
Anxiety has a way of making uncertainty feel urgent. When something feels unresolved, your mind may tell you to keep thinking, keep checking, or find one more piece of information before you move on.
For problems that have concrete solutions, this can be useful. If your car starts making an unfamiliar noise, investigating the cause may eventually lead to an answer and a repair.
Existential questions are different. If your mind asks, “How can I know with absolute certainty what happens after death?” there may not be an amount of research or analysis that can provide the level of certainty your anxiety is demanding.
You can spend hours thinking about the question and still arrive at the same place: uncertainty.
When this happens repeatedly, researching and analyzing can shift from genuine exploration into a strategy for reducing anxiety. The more you rely on that strategy, the more your brain can learn that uncertainty is something you need to resolve.
Existential anxiety and OCD
For some people, existential fears can become part of an obsessive-compulsive cycle, sometimes referred to as existential OCD.
In this case, the person may experience recurring doubts or intrusive questions about reality, existence, death, consciousness, identity, or meaning. The questions themselves can vary, but they tend to produce a strong urge to find certainty.
Compulsions may not always be obvious from the outside. Many are mental. Someone might repeatedly review arguments in their head, check whether reality “feels real,” analyze their own consciousness, seek reassurance from other people, research the same topics online, or test different explanations to see which one makes them feel most certain.
The relief these strategies provide is usually temporary, which can lead to another round of questioning.
Not everyone who experiences existential anxiety has OCD. A mental health professional can help determine what may be contributing to the anxiety and which treatment approach makes the most sense.
Recognizing when you’re trying to eliminate uncertainty
One helpful step is learning to notice the difference between engaging with an interesting question and becoming caught in an anxiety-driven search for certainty.
You may be caught in the latter when you find yourself repeatedly:
Googling variations of the same question
Reading philosophical or scientific explanations primarily to feel reassured
Asking other people what they believe so you can compare it with your own beliefs
Mentally reviewing arguments or possibilities
Trying to prove that a feared possibility cannot be true
Searching for the “perfect” explanation
Checking how anxious or certain you feel
Reassuring yourself that everything is okay
Trying to force the thought out of your mind
These strategies are understandable attempts to feel better. However, when they become repetitive, they can reinforce the idea that you need to resolve the question before you can tolerate the discomfort it creates.
You don’t have to answer every question your brain asks
One of the shifts that can be helpful in working with existential anxiety is recognizing that a question can exist without requiring an immediate answer.
Your brain might ask, What happens after death? You may not know.
It might ask, What if life has no objective meaning? Perhaps there is no way to know with certainty.
Or it might ask, How do I know reality is real? Again, absolute certainty may not be available.
Instead of entering another round of analysis, you can practice noticing the question and returning your attention to what you were doing. This is not because you have discovered the correct answer or convinced yourself that everything is fine. It is because you are practicing allowing uncertainty to exist without treating it as an emergency.
The goal isn’t to stop having existential thoughts
Trying to completely eliminate existential thoughts can make you even more attentive to whether they are occurring.
Instead, therapy may involve learning to notice these thoughts without automatically engaging with them. You might recognize, There’s that question again, notice the discomfort that comes with it, and resist the urge to immediately debate, research, analyze, or reassure yourself.
This is different from replacing the thought with a comforting answer.
Rather than telling yourself, I know everything is going to be okay, the practice becomes closer to: I don’t know the answer to this right now, and I can allow that uncertainty to be here.
Over time, this can help reduce the amount of attention and importance given to each new existential question.
What if the anxiety feels overwhelming?
When existential fears are part of an OCD cycle, Exposure and Response Prevention (ERP) can be particularly helpful.
ERP involves gradually approaching thoughts, situations, or uncertainties that trigger anxiety while reducing the compulsions used to obtain reassurance or certainty.
For example, someone who repeatedly spends hours trying to determine what happens after death might practice allowing the possibility, Maybe I will never know, without immediately researching, analyzing, or asking someone else for reassurance.
The purpose is not to convince yourself that a feared possibility is true. It is to practice experiencing uncertainty without automatically trying to make it disappear.
Over time, this can help your brain learn that uncertainty may be uncomfortable, but it does not always require a response.
Curiosity vs. anxiety-driven searching
Working on existential anxiety does not mean giving up your interest in philosophy, science, spirituality, or the bigger questions in life. You are still allowed to be curious.
The difference is often found in why you are searching and whether you are able to stop.
Curiosity might involve reading about different philosophical perspectives because you find the topic interesting, considering what you have learned, and then moving on with your day.
Anxiety-driven searching often feels much more urgent. You may feel that you need to find an answer because you cannot tolerate the possibility of not knowing. One article leads to another, reassurance wears off quickly, and each answer seems to create a new question.
The behaviours can look similar from the outside. What matters is the function they are serving and whether they are helping you engage with your life or keeping you trapped in a cycle of certainty-seeking.
Learning to live alongside unanswered questions
There will likely always be questions about life that cannot be answered with complete certainty. Learning to tolerate that reality does not mean giving up on curiosity, meaning, or the things that matter to you.
You do not need to solve the meaning of existence before spending time with someone you love. You do not need to know exactly what happens after death before enjoying the life you have now. You do not need to know with certainty that every decision is the “right” one before making choices about your future.
Sometimes, the most helpful response to an unanswerable question is not another answer. It is allowing the question to remain unanswered while continuing to participate in your life.
That may sound like: “Maybe. Maybe not. I don’t know—and I’m going to keep living my life anyway.”
When should you seek support for existential anxiety?
Existential thoughts are a normal part of being human. However, it may be helpful to speak with a mental health professional if these questions are causing significant distress, interfering with your sleep, relationships, school, work, or daily activities, or leading to hours of rumination, reassurance-seeking, checking, researching, or avoidance.
For some people, these patterns may be related to an anxiety disorder or OCD. Treatment will depend on what is driving and maintaining the anxiety. When obsessive-compulsive patterns are present, evidence-based approaches such as Cognitive Behavioural Therapy (CBT), Exposure and Response Prevention (ERP), and Acceptance and Commitment Therapy (ACT) may be used to help someone develop a different relationship with intrusive questions and uncertainty.
