i really just dont know who i am anymore

since february i have "POcd". Initial symptoms were thoughts, but then I did a testing compulsion during an intimate time, and I spiraled ever since. I struggle with addiction to smut. I'm cutting that out, but I feel as if it is too late. Ive never experienced this much mental, and emotional anguish in my life. On my time on this application I have given advice to others, and helped around, but I wonder if that even applies to me. Millions of times I wish I could turn back time and be more careful. I want to prevent many things, including what led me to spiral into OCD in the first place. I'm surely having an OCD episode. I have gotten a diagnosis, but I'm still not sure. I feel evil, cause unlike many here, I tested on my body sensations and it backfired (twice) I know I'm not supposed to figure out why that is the case, but now I have to live with it for the rest of my life even if its something I don't desire. This is disgusting for me, it is abhorrent. I could've never seen this coming. Day by day I've become more fearful of living with this, "OCD". I was a normal person before this, I knew what I was attracted to, I know my preferences, so why did this come about? This is singlehandedly the most painful thing that has happened to me and I have nobody but myself to blame. I am scared of death but I also would'nt mind sleeping for years on end. My parents and brother were understanding of my situation, but I failed them regardless. I don't want them to see me this way, nor do I want them to learn more of my predicament. I'm cooked. I know it, Fin, thats all folks. I'm only 20 and I already have other diagnosed mental illness so I recklessly brought upon myself another one. Its agonizing to live through, I wish this on nobody, not even my worst enemy. I can't even identify myself at this point. Its tearing me apart.

Im tired of knowing that people have blocked me on NOCD for my pocd / real events ocd posts... Im tired of knowing that I have real events that are POCD related... Im tired of getting intrusive thoughts and false memories of the worst case scenario for my pocd and real events ocd being true... Im so tired of it all...

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.
