Think about my brother's performance.

Everyone has his own value when he comes to this world. Don't think about this suicidal idea. This is a sign of cowardice, because your life is not just yours. God sent you to a miserable family, but he also had a purpose. You must fight bravely. Don't feel inferior. There are more people suffering in the world than you. There's nothing to feel inferior about. If she hates your home, she will find a girlfriend. So don't worry about such a woman, learn to live, find a job, don't think about what makes you uncomfortable all day, just be happy. I don't think your brother wants to see you have a bad day. You still have your parents and relatives. You don't have nothing, live bravely. Send you two words: work hard!
