Why does these thoughts feel so real, it feels like I really want what my thoughts are telling me 😞

Ii spoke w my bf this weekend and he mentioned that he has thoughts just like me, but his don't bother him like me. I then felt a lot better and he tried dissecting one of his thoughts like I usually do and realized it felt more real for him after. That made me realize that none of my thoughts were ever true and I blew them up. However, yesterday I had a thought ab “wait wut if you liked that one guy? How dare you bc youre supposed to love your bf and not secretly like someone else” and treated it as I usually did bc I accidentally wanted to see if it was true but didn't rlly but I would check to see if it was there and now that thought feels so so so real now and I feel really bad how do Ik it's not real? I feel so bad and guilty bc lividly this makes 0 sense but it feels so prominent. It felt pretty real when it happened yesterday too. And now I feel awful bc how is it possible after my clarity the other day? Why does it feel so prominent 😞😞😞

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 🥹???!!??

Can ROCD make your thoughts and feelings feel 100% true or real???? Like I can have a thought or feeling and in that moment it feels real or should it not feel real until the ocd latches onto it?
