cw: severe mental health issues

when I was little, my mother would chronically ignore me and my problems in favor of my brother because he "needed more help than me." we have the same mental disabilities (ADHD Autism) but because my brothers meltdowns were a lot more noticable and I internalized it more, my mom focused on the one who's issues were more explosive. we both also have severe depression but again, mine was ignored in favor for my brother because I needed to "stop trying to be your brother." it made life incredibly difficult and when I developed BPD because of everything going on at home, things got seriously worrying. my BPD started getting really bad and I went down a dark path: I was hallucinating, skipping school everyday, hurting myself, doing harder drugs, not sleeping, incredibly depressed, etc. I was hospitalized 5 times in one year and was going to multiple different therapists, I quickly started being the thing that my parents had to focus on. I'm now the one that "needs more help" and it's a very weird thing to grapple with.

can anyone else relate?
