Does the guilt that comes with pocd ever go away? Or is it always gonna be there

I can’t help but feel so anxious because of guilt. I feel guilty about not sharing everything about my OCD to my partner, but because I understand that confession itself is a compulsion and would not help anyone. I feel so anxious too that if all my fears come true and she finds out, then it would be so devastating for everyone especially her. Does anyone feel the same thing? How could I change my perspective on this?

I'm doing ERP to beat my 3.5 long POCD with groinal responses. This implies walking near kids and trying to loosen up my hyperfixation on groinal responses (not caring about what I feel there). Obviously ERP is distressing. In fact, being scared is probably a good sign in this context, because it means I'm doing my exposures correctly. However, what's much more scary is that in all of these years of OCD there were countless times when I experienced actual muscle contractions/retractions in groinal area. And I can't tell if all of those were accidents. Sure, I don't want to do it (except if I'm relaxing muscles in order to avoid groinal sensations), but was it really an accident? And that's what is destroying me. I'm actively having those feelings near poor kids, even though I always believed myself to be a good person. Now there's no turning back. And I'm turning 18 in two weeks. How can I be enthusiastic about anything when I know that my OCD turned me into an actual monster. I want to continue ERP, but I can't imagine myself living on happily even if I somehow cure OCD

Can anyone who has dealt with pocd/harm ocd tell me if it ever gets better? I don’t even trust myself anymore and I’m so tired of it.
