"I can't stop thinking about it" is something I hear almost every week in session. A conversation replayed for the tenth time. A decision turned over so many ways that it stops making sense. A message re-read, re-drafted, and still not sent. Overthinking has a way of convincing us that if we just think about something a little longer, we will finally land on the right answer, the safe choice, the version of events we can live with.
Most of the time, that relief never actually arrives. In my work as a trauma therapist on the Gold Coast and Northern NSW, overthinking is one of the most common patterns I see, and one of the most exhausting to live with, because from the outside it can look like nothing is happening at all.
This article discusses overthinking, worry, and their impact on daily life. If you are currently experiencing significant distress, please reach out to a mental health professional or call Lifeline on 13 11 14.
What Overthinking Actually Is
Overthinking is the act of dwelling on the same thoughts, decisions, or situations over and over, usually without reaching any new insight or resolution. It can show up as replaying past events, obsessively planning for future ones, or getting stuck analysing a decision until it feels impossible to make.
It is worth saying clearly: thinking things through is not the problem. Reflection and planning are useful, healthy parts of how we navigate life. Overthinking is different. It is thinking that has stopped serving a purpose and started running on its own, often fuelled by anxiety rather than genuine problem-solving.
Problem-solving moves toward a decision. Overthinking moves in circles. That distinction is often the clearest way to tell them apart.
Why We Overthink
Overthinking often develops as an attempt to create certainty in situations that feel uncertain or unsafe. If you grew up in an environment where things could change quickly, where mistakes were met with criticism, or where you had to anticipate other people's moods to stay safe, your mind may have learned that thinking ahead, a lot, was a form of protection.
Perfectionism plays a role too. When there is a strong fear of getting something wrong, the mind can try to eliminate that risk entirely by considering every possible angle before acting. The trouble is, there is no amount of thinking that can guarantee a perfect outcome, so the cycle never quite reaches an end point.
- Moves toward a decision or next step
- Feels focused, even if difficult
- Considers a few realistic options
- Has a natural stopping point
- Leaves you with a plan
- Circles the same ground repeatedly
- Feels anxious, tense, or draining
- Spirals into unlikely worst-case scenarios
- Has no clear end point
- Leaves you more unsure than before
How It Shows Up in Daily Life
Overthinking rarely stays confined to one part of life. It can show up as difficulty falling asleep because your mind won't stop reviewing the day. It can look like sending a text and then rereading it forty times, searching for a hidden meaning that was never there. It can mean spending hours weighing a decision that, in the end, would have been fine either way.
Over time, this pattern takes a real toll, on sleep, on concentration, on the ability to simply be present with the people around you. Many of the people I work with describe feeling tired in a way that rest doesn't seem to fix, because their mind rarely gets a genuine break.
Overthinking is not a character flaw. It is usually an old strategy that made sense at some point, the mind trying to protect you by staying one step ahead. The goal is not to force yourself to stop thinking. It is to gently teach your nervous system that it is safe to land somewhere.
What Actually Helps
Name it when it starts
Simply noticing "I am overthinking this" can create a small but important gap between you and the spiral. That gap is often enough to make a different choice.
Set a decision deadline
For everyday decisions, give yourself a real cut-off, five minutes, an hour, end of day, and commit to deciding by then, even if it doesn't feel perfectly resolved. Most decisions can be adjusted later if needed.
Get it out of your head
Writing thoughts down, even messily, moves them from an endless internal loop into something you can actually look at and evaluate. It is far easier to see a thought is unreasonable once it is on paper.
Regulate before you reason
Overthinking is often driven by an activated nervous system, not a logic problem. Slow breathing, movement, or grounding techniques can lower that activation enough for clearer thinking to actually be possible.
Ask what you would tell a friend
We are often far more reasonable and compassionate toward other people than we are toward ourselves. Stepping outside your own perspective, even briefly, can interrupt the spiral.
When to Seek Extra Support
Everybody overthinks sometimes. It becomes worth addressing with support when it is affecting your sleep, your relationships, your ability to make decisions, or your general sense of ease in daily life. Persistent overthinking can also be connected to anxiety or past experiences that are worth exploring with a trauma-informed therapist.
You do not need to wait until it feels unmanageable. Learning to work with your mind, rather than being run by it, is possible, and often makes more difference than people expect.
Is overthinking a mental health condition?
Overthinking itself is not a diagnosis, but it is a common feature of anxiety and can also show up alongside depression, OCD, and past trauma. If it is persistent or distressing, it is worth exploring with a mental health professional.
Why do I overthink more at night?
With fewer distractions and a quieter environment, the mind has more room to wander, and the body's natural wind-down process can leave you more emotionally exposed to worry. Many people notice their overthinking is worse right before bed for this reason.
Can overthinking be a symptom of anxiety?
Yes. Overthinking is one of the most common ways anxiety shows up. The mind tries to reduce uncertainty by analysing every possible outcome, which can feel productive in the moment but usually increases anxious feelings over time.
How long does it take to stop overthinking?
There is no fixed timeline, and the goal is rarely to eliminate reflective thought entirely. With consistent practice and, where needed, therapeutic support, most people notice a meaningful reduction in the frequency and intensity of overthinking within a few weeks to a few months.
Should I see a therapist for overthinking?
If overthinking is affecting your sleep, relationships, work, or overall wellbeing, therapy can help. A trauma-informed therapist can help identify what is driving the pattern and build practical tools to work with your mind rather than against it.
