AITA for calling my brother a fat loser who will be homeless and causing my mom to crash out

so this all started yesterday and for context:

i have a morbidly obese autistic bipolar and schizophrenic (i know) brother and he’s 32 now he has no job no higher education and all he does is bother my mom all day for food and arguing with people in the house . he’s not allowed to drive cause he’s crashed a million times and has gotten in trouble with the law and still fighting in court for his shitty behavior. he’s been kicked out out countless schools for being a peeping tom and sexually harassing women all over campus.

my mom is in complete denial about this and thinks that he’s just not aware of his actions. she complains day and night about being his primary caretaker but does nothing to change the situation (money is barely and issue in our case)

we have pleaded for her to send him into a facility cause she’s has reached retirement age and is going to law school soon on top of this to achieve her life long dreams but he keeps holder her and honestly everyone back because who tf will take care of him?

Here’s where the problems really come in. Last night the entire family got into an explosive argument because my father was fed up with both of my brothers (one i haven’t mentioned) for being dead beats and she just keeps on defending them and cursing us out whenever we hold them accountable for anything and went as far as to call my other sister for calling their behavior out a Jezebel (basically a misogynistic slur in our country) this is where I really get pissed and cursed her the fuck out

I called my brother a fat (r word) who will end up as a crackhead by the time they pass if don’t get him into a facility this was because she insisted for the 50 millionth time that she will set him up with a wife to be his full on caretaker as the long-term plan for his future. she started crying and arguing and hung up on me then the next morning she sent me a video about a mother who was so heartbroken by her family she cried herself to sleep then died. this reaction is actually the type of the iceberg because prior to this when everyone else was telling her the same thing, she genuinely started, screaming and wailing, and cursing everyone.

I’m so torn on this because part of me feels like I was too harsh, but I’m so sick of this.
