Had my first erp session today and it was hard shall I keep going ?

I’m starting NOCD. I had several years of cbt as a child (well over 20 years ago) and I see a trauma therapist. But now I’ll be seeking further help for OCD and just really scared. CBT wasn’t helpful for me. How has ERP been helpful for you? Do you feel like you’ll finally get your life back? I’m consumed by my obsessions 😢 Would love others feedback if ERP helped you ❤️

Exposure and Response Prevention (ERP) isn't always easy, but as one of the most effective treatments for OCD, it's worth it. If you've started ERP, what has been the biggest surprise you've experienced in learning to resist compulsions? If you haven't started ERP yet, what is holding you back from starting?

How long should I do ERP, so that my brain gets used to it, not to say tired?! I've been working for about three months, but everything still seems vivid in my head, there are even vulgar words in detail... since the sexual topic is both a groinal and a feeling that I want to touch myself. It's mostly related to faces and genitals, so how exactly can that go, if it's emphasized that sex pictures in themselves give that feeling, whoever is in them?
