What else could I do to detach ?

I've done everything I can, well I think so. I tried venting here, I've read articles on how to get over a breakup, watching videos too from psychologists nothing helps I failed to respect my own boundaries by texting him again and stalking him as if it wasn't clear after everything he's done that he doesn't want me but it is still like my mind is in denial and a state of shock is like I can't see reality I'm not ready to let go

I just keep ruminating or lying to myself that everything would be fine when im not sure if that's truth or if i would ever be able to feel okay again

I don't know how I got to this point I go from feeling numb to getting anxiety I cant even eat I can't concentrate I just reached for temporary distractions

I don't know how to deal with it anymore is so bad im telling looking for closure and comfort by the same person who hurt me
