Anyone else with existential OCD where you question whether or not you or anything else actually exist?

I’m really struggling with this theme because it can make me feel “fake” and it creates doubts that the world around me isn’t real or it’s a simulation? I’m really trying to expose myself but even the possibility makes me incredibly afraid. It even plays into my suicidal ocd as well and makes me afraid that my life would be miserable if this was true. I know how ocd works and I know not to fully believe that. But at the same time, I am trapped in doubt and fear. How could I possibly accept this? Will I ever see the world or life the same again? (Don’t answer that I realize that’s reassurance). Idk this theme is so ass.

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.

Hi everyone, this is my first post on the forum, and honestly, it’s one I wanted to use to reach out and feel a little bit less alone, and possibly ask some advice to people who have been where I currently am! I have gone through a few OCD themes over the years, including harm OCD, POCD, moral scrupulosity and a few other smaller themes, but in the last year I’ve really hit Existential OCD hard, as I’ve managed to accept and move past all my old themes. It started out quite “normal” for Existential OCD; Solipsism fears, Simulation fears, am I even real, what even is real kinda stuff, that I’ve often come across when looking at other people’s experiences. I’ve done a lot of work to move past these themes and have had a good level of success. But recently, and this is what I really wanted to reach out and see if anybody else has experienced something similar; I’ve found that I’ve started experiencing fears around more physics based things, I was freaked out by the fact we are made up of atoms and how can we be us if we are a load of little floating items, I was freaked out by things like multiverse theory, black holes and many many more physics based concepts. I’ve been struggling to move past these as, as my brain keeps reminding me, they are real, proven concepts as opposed to things like simulation theory which, maybe is, maybe isn’t. Has anyone else been down this road after the “normal” existential topics? And could you share some insight into how you might have moved past these particular fears that are more grounded in real concepts as opposed to more philosophical ideas? Thanks guys!
