Have you been told by your therapist exposures don’t help with rumination?

I find while doing exposures, rarely does my anxiety lessen. It usually amps up and stays that way for the remainder of the day. I could be having a fairly decent day, but dutifully do my exposures and then the rest of my day is anxiety filled. I guess that’s just how it is now? Also, I’m wondering if my therapist even believes I have OCD. I totally understand my therapist cannot provide reassurance. But it’s to the point it seems my therapist acts like I actually did the thing I fear. I feel so isolated.

My biggest is ruminating, i talk and talk and over share with myself and others Like what are some exposures?

When I catch myself doing compulsions mentally during exposure sessions, it seems alot of the time like the realization that I was just doing a compulsion is more distressing than the actual trigger I'm trying to expose myself to. It feels defeating having to admit the prompt at the end that I performed a compulsion yet again. I still think I've made progress overall, and generally speaking I don't think I'm performing compulsions as much as I used to, and my distress has also gone down noticeably (not completely) but exposure sessions have been kinda tricky for me from the beginning since its all mental. Additionally, I am a bit concerned that I could start using exposures to rid myself of anxiety rather than expose myself to it properly.
