1. It's Caused By Anxiety

Firstly, so much of the fear about Depersonalization being a permanent condition can be put to bed by understanding a simple fact:

Depersonalization is an anxiety-spectrum condition.

That's not just me saying it -- it's what all the scientific and anecdotal information says too. The feelings of detachment, the strange fear, the anxious thoughts - all of it is caused by anxiety.

Depersonalization is your brain's natural response to trauma. That may be from violence, a car crash, a panic attack, a bad experience from smoking weed etc.

Your brain thinks it's in danger, so in order to deal with the perceived trauma, it kicks in with 'fight or flight' response. This has two results:

A: Your body goes on high alert. This means that your pupils are dilated, your hearing is more sensitized, your heartrate increases.

B: In order to get you out of the dangerous situation, your brain 'pulls you away' from the danger. This basically means that when you're faced with danger, you don't curl up into a ball and cry! Your brain makes you feel disconnected from the danger so that you can remove yourself from the situation. This is why so many people report walking calmly out of car accidents or burning houses calmly, or with no recollection of the incident at all.
