I'll get moments of DP/DR that do pass eventually, I just have to sit, wait and watch or use grounding techniques, focusing on my surroundings in the present.

I've seen and have visual hallucinations that things looking unreal doesn't bother me anymore.

I don't know if there is medication for it, but talk therapy is often used. If it's really disturbing to you, then talking to a T needs to be.

Good luck!
