It Comes in waves .. at school mine tends to get intense probably because of overwhelmingness or stress , but that's not always what causes it because I can be chilling at home and it happens. It's like when my mind works harder than it should it kind of happens. But look you can't let his get to you to a suicidal level.. I know that's how it feels when it happens though believe me. My derealization made everything look like paper flat little holograms it was extremely distressing. Just know .. it's been 6 months and finally started getting better around the 3-4 month mark (I got mine induced from weed) .. sometimes thing will still appear a little "off" but it's never as severe as it was. As long as it's bareable that's all that matters. I suggest putting sunglasses on , it's been known to help bc it prevents more stimulation to eyes. Also I can do this thing where I make my eyes purposely blurry, and it helps too. Whatever you do , try to relax. Read recovery stories. There's tons of hope. Dont rely on medicine .. until you really think this shit is permanent like I mean you've had it for a year or two. Then you can look into stuff like naxolone which has been known to help with dissociation. When I had it really bad I always had the thought "okay there's medication that can help me worst case scenario" in the back of my head .. just to keep me sane. But it's true! Hope , is amazing.. when it comes to dp and dr. And it's actually everywhere there's just a lot sufferers so we can't see i. Whatever you do just don't look up people suffering or horror stories online , it can make it so much worse because you'll see their symptoms and wonder if you have them and think about them causing you to have them. Don't do it , please take this warning as a blessing it made things so much worse for me.
