I like to make fun of my brother
What do you want to say about him?
He is such a loser, he spends all day on his video games and he can't accomplish anything in life
Your brother doesn't deserve all this hate you are throwing at him. You need to be nicer to him, you are essentially a bully and are making his life miserable.
Oh, so he's also on drugs now.
That is not good. You need to support him and help him instead of ridiculing him so that he can get better.
