Trying to move past something and not seek reassurance but it's honestly one of the hardest things I've had to do

I'm struggling really hard with relationship obsessions. Do I really love my partner? How can I know? Am I really just faking it? That kind of thing. It's making my life and relationship a lot harder than they need to be. I could use a few helpful coping mechanisms, trying to move away from less helpful ones like chasing reassurance.

So hard to not engage the thoughts because even though it's from the "past" (i don't even know if im remembering things correctly and it kills me) and i can't change it, I just NEED to prove it to myself that it didn't happen this way. If you'd asked me questions maybe a few months ago, I would have been able to lucidly explain things. Now I just feel like I'm in a constant swarm of thoughts, not knowing if anything is real. If my brain is to be trusted. Wish I could just get hypnosis to forget

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 😭
