AITA for telling my mother I hate my special needs brother
For context, my brother is 19, and is diagnosed with autism and learning disabilities, meaning he doesn't communicate in any form other than repeating things from TV, and doesn't understand much socially. I've not once had a conversation with him. I've grown up with everything revolving around his needs and demands, from going home from school early as a kid to get him, to listening to him shout every two minutes at home daily. Since I've spent all my life around it, it doesn't particularly bother me.
Recently, since he's an adult, the laws in my area mean that if he was taken into hospital, and then a mental hospital, he'd be out of reach from my parents and anything could happen. With him being prone to stripping in public during meltdowns, it's likely. My mother constantly seems stressed from looking after him.
I dislike him because he's inconvenienced my life so much, I cannot go out and see friends at all, I cannot say certain words or he'll shout and throw things, I cannot tell him to stop making noise or he'll do it more. My parents abide by his every demand because they can't argue with him. One night it simply got too much, and during an argument I told my mother that I hate my brother. She still asks for me to accommodate everything for his needs. AITA and what do I do?
