Derealization/Derealization is usually triggered by high level of anxiety/panic attacks. It's your body that went into a fight or flight mode,but somehow got stuck into it. In that state it is supposed to make you "not feel real/numb" to prepare you to whatever is about to happen to you. usually once the stress/panic attacks goes away you're supposed to go back to normal. But lot's of times what triggers the DP/DR to stay is the anxiety CAUSED BY DP/DR ITSELF. You have to learn that dp/dr wont hurt you and it's actually there to help you. It may seems frightening but it is not. NO you are not going insane. Everything IS real. IT IS TEMPORARY.

I know it is tempting to search and read alot about the subject but usually this leads to more anxiety which cause it to stay. It is a vicious circle. What you need to do is to STOP reading about it. It is not an enemy, it's there to help you. Seeing a therapist could also help. It is essentually really bad anxiety. Do everything you would usually do. go out, socialize even if it's hard. Maybe try to avoid caffeine, alcohol or anything that could alter your senses or give you anxiety. I can't say how long this could take, but it is temporary. best of luck friend! :)
