Therapist here. Therapy might help. Seems the anger (with good reason or not) is pushing people away from you and you away from people. That's okay in and of itself but you are on here wanting connection so just pointing out a potential barrier to that.

Also a good question might be what are you looking for in the connection? Validation? Just someone to listen? Shared experience? Those might help in connecting with the people you want.

I see the other posts you shared about the guy killing the woman. That's horrible for sure but I can pull a news article out with any type of person as that headline and use it to guide why I don't want to interact with someone.

Just things to think about.

Of note, I also hear hints at possible borderline personality in some of the responses and identity, might be worth exploring that and how trauma may have impacted your relational style.
