Is anyone else experiencing derealisation ? If yes how long? What do you do to face it?

I think I have if it’s when you are questioning whether you are real or what’s around is real? I considered it a part of existential OCD. I’ve been dealing with that for about 3 months, it was triggered when I received the news that my grandpa passed away. I’ve been doing ERP self-recordings where I speak out my fears and listen to it over without compulsions. It seems to help a bit I think because it has been declining slowly

I’ve had cannabis induced dp/dr for four years now, it’s gone away but it was triggered again last year. Honestly what’s helped me most is telling myself that I am in control, I keep repeating that to myself when it gets rlly bad bc sometimes it feels like I’m gonna lose it but I won’t, bc like I previously stated you are in control and in charge. Also, try not to pay attention to it, don’t ask yourself “oh do I feel it now” “am I gonna get dp/dr today” etc... I don’t recommend this to everyone but I used to keep a rubber band around my wrist and I would pinch myself with it (very lightly!!) for whenever I would feel out of it and felt like I was about to start panicking. On the bright side, dp/dr is NOT PERMANENT, it’s not considered a disorder, it goes away with practice and time because it’s just a defense mechanism the body uses when overly stressed, depressed, traumatized, etc.. wishing you the best of luck!

What helped me was having a shock like a really cold glass of water or a loud noise would scare me back to reality Maybe not the best advice but it worked for me ? Wish you the best :)
