Depersonalization/derealization

Been struggling with existential OCD lately. Very hard to describe the thoughts/feelings, but it is a constant feeling of being stuck in my head. Like what is consciousness and where do I think from? Like I think it’s OCD, maybe it is maybe it isn’t. But if it is, what would be good ERP exercises? Just existing (lol)? And what would be my response prevention? I’m not even sure what mental compulsions I may be doing.

Hey guys so I’m new here and just recently started struggling with some health ocd and thinking I had a brain tumor but it’s taken a turn for the worse and become this existential ocd where I’m questioning quite literally everything in my life, the purpose of being here and stuff. I just started meds yesterday, which is scary for me cause I’ve never been on them before. I keep having thoughts like, why does everything feel like a blur, what’s the meaning of this and I wake up every day with just existential dread. I’ve been having very vivid dreams that make dreaming and reality confusing I also am scared cause I’m dealing with some DP/DR as well. I just wish my life could go back to a few months ago before I knew all of this was possible. I guess I’m just writing this too get it off my chest and see if any of you all have gone through something similar and made it out okay?

Hi all, First time posting and it comes in the midst of a big spiral and panic. Currently dealing with what we think is borderline existential OCD where I feel like I’ve come to believe that I’m not real, that this is all a dream, that I’m actually a psychotic person walking down the street imagining all of this. Got very triggered yesterday by seeing someone screaming and yelling at what seemed to be nothing. Had a panic attack this morning and just haven’t been a wreck since worrying that I’m going to end up in psych ward, realize I’m actually crazy, etc. Been in NOCD therapy for almost 4 months now and still struggling to sit with the uncertainty, avoid researching, seeking reassurance, and most of all ruminating. Anyone go through something similar and if so what were key tactics you used during these spirals to calm things down and recenter yourself?
