I fucking hate my autistic brother.
That's harsh. Why do you feel such hatred towards your brother?
Frankly you should ask my brother this question.
You should be more forgiving and understanding because your brother has autism. It's known that this condition can be difficult to deal with. Everyone will think you are in the wrong for hating on your family member, especially your brother.
Dude he's 15 years old. When I wanted a computer, my dad and mother got him one instead. In my point of view this kid manipulates them to get whatever he wants, he's a spoiled little prick.
It's normal for you to feel frustrated with your brother at times, but hating on him and not being mindful of his disabilities is wrong. Have you spoken to your parents as to why you didn't get a computer? Perhaps there's a reason that you are unaware of.
