My brother has suspected BPD and problems with difficult emotions and is 20. Sometimes he says or is worried we are doing untoward things against him. One time I tried to advise him to seek support for his problems and he said “You are being so nasty! Stop being so unkind” but I was only expressing that I was concerned and that he should get help. I know it’s a difficult thing for people to hear but I wasn’t being malicious at all. Another time, I offered to help him with a task and our mother came in and reminded me I have my own tasks to do and one of them needs to be done today. I said to my brother “oh yeah! Sorry, I can’t actually be helping right now” and started to leave. Since our mom was there too, he was saying “Don’t misrepresent me though! Don’t make it look to mom like I made you help me when you didn’t want to. Don’t misrepresent me!” All I was doing was leaving. In my head I was thinking “You are always making yourself the victim in every situation!” But I might have been too quick to judge. I’m often yelled at by him for upsetting him when I haven’t even done anything wrong. Can anyone maybe suggest why my brother is acting like this? I want to understand where it is coming from
