For context, I'm 17(Autism/ADHD/Tourettes/PTSD), my younger brother is 15 (adhd and a whole plethora of other stuff, but not likely autistic), my mom is 43(NT(?)). I have two older half brothers (23 and 21) who have autism and adhd respectively. I live with my mom and younger brother.

My younger brother has severe anger issues and is likely a narcissist, much like our father (who we haven't seen in over ten and a half years). He gets mad at me whenever I try to talk to him, and doesn't like when I do/exhibit certain behaviors that comfort or bring me joy.

Whenever this happens, I try to explain myself to him calmly, and he gets more mad and even threatens me with violence or death. He's in therapy, and is on medication, and has been for years, but none of this shit is working for him. His behavior is part of the reason I was majorly suicidal in middle school.

But, after my brother leaves the room, my mom scolds and chastises me for antagonising him and not reading the room.

Like, he came into the room totally calm! How the fuck was I supposed to know he was mad? And then she said, "It's shit like this that makes me feel like i have three separate families."

Like, that's not my fucking problem, maybe, if you had just reprimanded your child better (or better yet, send him to military school!) instead of giving into his every demand, then he wouldn't be such a complete asshole. But no, blame it on the autistic child who has trouble confiding with adults and would rather confide with strangers on the internet.

He also tries to bait me/trigger my Tourettes into saying certain slurs by saying words that sound close to the slur but aren't the slur then gets mad at me when I ask him to stop.

And he also tells lies about me to our relatives, I'm certain of it, he's a compulsive liar and they just seem to love him more. I've always been an outlier.

It's times like this where I fucking hate being autistic, because I literally cannot read the fucking room, THAT'S PART OF MY AUTISM, MOM. YOU ABSOLUTE KNOB.
