Why does ocd have to feel so real. I don’t even know if I have it or not, I’m terrified

i’m terrified to get a diagnosis. What if it’s not actually OCD??? I made a list of reasons why i think so and then i think what if im lying and i actually don’t do this stuff and am just dramatic and i just want to have OCD so then my thoughts are justified?? I have struggled in the past year with Pocd & Rocd and then also some bits of thinking im constantly in danger or being watched? I’m scared.

Is ocd supposed to feel like a genuine belief ? I see or hear some people saying things like « I know it’s not true but …. » while I personally don’t « know that it’s not true » I feels genuinely real and I even find evidence for it

I have really bed harming intrusive thoughts and sometimes feels like it’s feeling! The thoughts happening every day and the hardest part is that I’m testing my self in head all the time if that’s what I am or want!!! Also, so many times feels like I’m been tricking myself and doctor or people and maybe I don’t have OCD, just that maybe it’s me really!!!! How can I know who I am really 🥹???!!??
