i need help/harm ocd

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.

i was recently diagnosed with ocd and i think im having a hard time identifying what is my ocd and what isn’t? or im not really sure how to express myself but i feel like i still don’t really know much about ocd and feel like an imposter saying i have it because i don’t know enough about it to really understand it? like all my life these things i would do or say or think or feel were i guess “normal” to me,, so how do i move forward when i don’t know really where to begin?

Finally slept well today! Which is nice. Regardless, I feel like it has destroyed who I am. Its been over a year and a half, and I keep overthinking and questioning my identity and I can’t let it go to the point where I feel that my future is certain, even though I’ve liked myself the entire time and had a pretty stable idea of who I was. My mind has gathered enough proof. I love being a woman, and I don’t want a different body. I wasn’t born in the wrong body. I am obsessing over my voice, which needs no changes, and my chest. After speaking to a friend of a friend, I’m afraid I’ll want a sex change when I finally have a partner. I’m terrified. I don’t know if anyone can relate. I don’t know how to get over this and my first ERP session is in about a week. How do I even go about this? I feel like a monster to my own family.
