I’m scared that ERP won’t work because what if I just don’t have ocd

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.

What would I do for ERP if my OCD says because I didn’t do something correctly or remember something I will have panic attacks that don’t end?

I’m thinking about doing erp but my ocd is so severe the thought of accepting my fears happening to me makes me sick to my stomach. I also believe in the power of my words and saying I accept this Bad thing will attract it into my life. I’m not sure what I should do🥲
