Retroactive Jealousy is so debilitating

I’m gonna try to make this make sense, and any support or advice would be great. I have a beautiful girlfriend, who I’ve been dating off and on for a year. We were really rocky but got our shit figured out 4 months ago and have been strong since. I truly love this girl more than I’ve loved anyone. And I know based off the sheer amount of ocd that has come up on our relationship, that she means a lot to me. Me and her were in a friend group in 2022 and we never liked each other. However she had a sexual relationship with one of my old friends. Fast forward to now I haven’t talked to him in a long time and I don’t see it as an issue. However… I keep having this vivid flashback to him touching her some kinda way in 2022. I can’t remember exactly what happened or the details but it’s running through my head. I guess this is retroactive jealousy but it’s really almost hurting my feelings. I wish it would stop but I know ocd doesn’t work that way. I just wanna be happy with my girl and not upset at her past experiences

I genuinely can't help but feel irredeemable over every little mistake made or regret I've had. It's so up and down, but I just miss the certainty. Knowing "this is who I am." I'm so disconnected from myself. Like, I'm really, really trying. Today is really rough... I got triggered the other night, and it's been hell since. I've been fighting seeking reassurance. I want it so, so incredibly bad, but I know it won't help me :( Some days, I just don't want to be here. It's funny because yesterday I felt amazing until I got triggered. I just immediately spiraled after that. I don't know. Does it genuinely get better? Will therapy really help me? Sometimes, I think maybe this is the best it'll get, and that scares me. Sorry for the vent. I'm just feeling so overwhelmingly anxious right now. I can't even cry (due to Zoloft). It feels claustrophobic somehow, having all these emotions trapped inside of my body with nowhere to go 😭

I want to get thought this weird horrible period, it has been horrible. I am doubting everything. I’m not diagnosed but when I look at my past I’ve always been horribly anxious and worrying about health, death and basically everything while suffering from major a lot of insecurities stemming from bullying and lately a lack of intimacy with my partner, Every time I think I’m on the way out, or see some light at the end of the tunnel my mind always pulls me back in. It’s torture. I’ve always been insecure about how I look and I find myself comparing myself at other males and it’s made my self esteem on the floor. I have a girlfriend and prior to this we had a future planned and talked about kids (we’re still young, but it felt so real), this all began to bubble when we stopped being intimate and the loss of my job. I don’t know anymore how to move on, every day feels like a chore. The intrusive thoughts telling me I’m in denial, constantly thinking about men I’ve felt insecure about their looks compared to mine wishing I looked like them plaguing my mind. The false attractions, prior to this i was comfortable in acknowledging good looking men. However now my mind takes this as evidence, every single thing in my past seems like some form of evidence. Not having male friends, the comparisons, being questioned about my sexuality from siblings. I’m sorry if this is reassurance, I am just needing to get some things of my chest. Every time I think about my first real attraction or girls I found pretty/attractive or I liked my mind is like your in denial and then I feel horrible about thinking those thoughts as I have my girlfriend. I miss just being with my girlfriend and not having these thoughts and feeling horrible. I feel like a fraud and a horrible partner. I’ve tried to accept maybe, maybe not, but something always comes back. These 4 months have been terrible. I want to sleep without horrible dreams, I want to eat. I want to feel like myself again. Thank you to anyone who reads this. Hope you’re strong too.
