ROCD and uncertainty

I have been battling ocd for over a year now and it likes to switch themes. Currently, it’s attacking my relationship with my girlfriend who I’ve been with since I was in high school over 10 years ago. It first began as an intense feeling that I have to leave or break up with her over dumb little things. Then it changed into a lot of guilt for having any thought about another girl. And the worse is feeling this intense guilt for past things I’ve done in the past while in this relationship. We were so young and I was teenager, but I often found myself watching porn, fantasizing about real other people in my life, and getting off to other girls that I may have known. When I was younger I didn’t think it was bad and that it was just a normal teen boy thing, but 10 years later I have so much guilt about it. And yes I’m with the same girl now. We’ve had our ups and downs, but I know I love this girl and I’m ready to propose to her soon. Anyway, these past mistakes I did when I was younger make me feel like a cheater and I can’t stop ruminating about it. I feel like I have to admit every detail and person I’ve ever had a bad thought about. I feel like if I propose to her and don’t tell her everything, that I’m a lair and didn’t give her the full picture. And the other day one of the girls I thought was hot when I was younger, came up in convo and I just went downhill. Now she knows I deal with OCD and she is very supportive, I’ve told her before that I did some bad things, but never all the details. And that’s all my brain keeps telling me to do. I have so much tightness in my chest and just want to be able to breathe again. But everyone says to not admit or it’ll reinforce the cycle, I’m just not sure how everyone else does that. And at the same time, maybe I am a cheater and just simply a bad person. Idk! I never cheated physically or anything like that, but my past mistakes feel like I did. But again I may just be a bad person! Please if anyone has advice or is dealing with similar things, I’d appreciate the help!

I am diagnosed with OCD, ADHD, and mild depression. But my OCD symptoms are so prominent in my daily life where it feels debilitating. It comes in waves, there will be months with very minor symptoms and other times where it comes in random hitting me like a truck making me rethink life. I grew up having intrusive thoughts of all types, and a lot of them sent me over the edge because I couldn’t understand why things of such sort would cross my mind, things that I’m sure to this day that I’m incapable of or would never want to actually do. Yet I find myself in a constant cycle of trying to dig deep in the past and trying to figure out if I ever acted on any of the intrusive thoughts I can remember, yet ofc have no recollection of acting on them because they most likely didn’t happen. However, not having concrete proof of these things makes me not want to see another day sometimes. It is so hard to move into daily basis like this. I’m also in a happy healthy relationship and sometimes I get these thoughts of “what if I’ve done something awful during the relationship (for example, cheat, dishonesty, etc.) and can’t remember?” I know I would never do anything intentionally to harm my relationship and I think that maybe the idea of not having my partner sends me down a rabbit hole to think all these things. This mental fight is getting harder and harder. It feels unbearable. Does anyone have some fruit for thought, relate, or have any tips?

for a few days now I’ve been super anxious about my relationship. I’ve been anxious about it before but lately it’s been worse than normal. I’m in a very healthy and loving relationship, I love my boyfriend so much and he treats me so so well. The only thing is that I’ve been having scary thoughts that what if I’m lying to him and don’t actually love him? What if I don’t find him attractive? And like what if the only way to stop being anxious is to break up with him? I don’t want to leave him and I am so scared. I feel like I’m lying to him by not telling him what’s going on because he might think I’m actually going to leave him, which I’m really not going to. I have had anxiety since before we started dating and incestual and sexual ocd, then I got into a point where I started having religious ocd, and now I have ROCD on top of that I think. I’ve never been diagnosed but I’m going to therapy and figuring things out but I’m so scared. Idk what to do and I feel like if I talk to anyone they’re going to say I have to leave him.
