Will ERP make you worse before you get better?

I'm just laying here avoiding being an adult and wondering if during ERP the therapists are mean. Like, is it a "tough love" type of situation? That makes me anxious

Anyone else feel like they just sit there during sessions? Like I can’t wait for it to be over so I don’t have to do this twice a week anymore. I think I’m putting in effort but sometimes feels like a huge waste of time and I’m not making progress but maybe that’s just my ocd?

I'm trying to get my head around ERP. What is the best way to describe how it's a "solution." Imo I think OCD happens with people who are very concerned with their own genuine integrity and probably their own "morality." So when something (like an uncomfortable "real event" that actually happened) messes that up, it's hard to grapple with that...hence the endless rumination and trying to "problem solve" it. But the mind doesn't let you sleep (i.e. OCD) if something is controversial and doesn't sit with you. Or if you obsess over something and it's based on a rooted fear. You just can't "let it go," it has to be addressed and dealt with. But what happens when it is NEVER dealt with? How does ERP address that dilemma as a permanent solution? Or does ERP only address compulsions and anxiety, but it doesn't actually deal with the issue causing it. Do you ever get REAL peace of mind? Or is just something to make you feel "less anxious" etc? Thanks I just want peace of mind. I haven't had true peace of mind in several years.
