how real can ocd actually feel? like is it normal to feel this real..

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 🥹???!!??

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?
