I Dont No What Is Wrong With Me?

My dear, it sounds to me like you are depressed and anxious, perhaps over your brother dying so recently. My suggestion is that you ask your parents to help you get into some counseling so you can work this through. There is absolutely nothing wrong with asking for help for something like this. People of all ages have shocking things happen to them that they need to work through, and you are no exception. I wish you well, my dear!
