Sorry you feel that way. When I stalled once I told my OCD t I was worried that I was taking time for other people who needed her. She said I'm making progress even by acknowledging the stall. Sometimes just being there is progress.

That being said I have OCD, with the diagnosis etc. It isn't in my group of obsessions/compulsions to worry that it's fake or not real. But my compulsions are straight up measurable and noticable to anyone who spends time with me. I struggle far more with the compulsions than obsessions. Maybe it's an obsessive thought of yours though? I have friends on the O side of OCD who have expressed that they worry no one believes them, or secretly thinks they are bad. That is tough! But if you have a t experienced with OCD they should be able to reassure you what is OCD and what is something else.

I do hope you have a therapist who specializes in OCD. That is extremely important because most therapists do not have enough training to sensitively and effectively treat OCD!!
