I have been feeling rather angry recently because I have the impression that a certain person thinks that they have done nothing wrong, despite actually causing me serious emotional harm in a way that I explained to them, and that the big argument we had over the subject was just me being irrational and stupidly emotional over nothing, and that everything is fine between us and she can just continue valuing me like her convenience.
Probably not helped by the fact that, at the end of the argument, *I* ended up apologizing for being upset at *her* behavior. It was partly due to the fact that she was so inextricably tied up with the majority of my friend group and that if I cut her off, I would've probably had to cut off a lot of my friends too to avoid seeing her, but also because I am far too forgiving in the moment and end up regretting it later. Throughout the argument, it seemed like she hardly even tried to preserve our relationship and was instead just constantly trying to save face. She even had the gall to give me some condescending ultimatum about how "it's up to you to decide how our friendship goes" or something like that. She was completely unapologetic originally. Eventually I ended up apologizing to her for "approaching it in that way" and she made a quick apology herself, but later it seemed like she either completely misunderstood what the whole argument was about or didn't even try to understand and just brushed off what I was saying. Come to think of it, I sometimes doubt that any of my friends would bother trying to see me outside of being in a group with her. I sometimes get the feeling that they don't value me or my presence or think that I matter that much either.
I've been really, really angry recently -- at her and my other (supposed) friends and just in general, and it's starting to affect my daily life, even outside of their presence. I don't know what to do to handle this. Any advice you guys might have would be appreciated.
EDIT: It's worth noting that this was one of the few people (perhaps the only one) who I actually trusted, and that they acted in this way towards me was a major, major wound. Now I sometimes feel like I don't have anyone who I trust, not even just to talk to about all these serious weights that have been in my mind lately.
