Life is a mess?

wow that's a tough one...i wish i could help, but i don't think anyone can help you really except emotionally. You have to help you mom take control of your brother. He hits her and he's only 9!! Imagine what he's going to do when he hits puberty! If he does it again take charge...lock him in his room or something! He has to get serious punishment, and for whatever reason your mom can't do it, you have to try! Tell her it'll get worse if she doesn't get help from somebody to control your brother. I don't know what to do about the whole bf story...but you have to have a serious talk with him and tell her to f off. She's not a best friend, trust me, that's not real friendship! About your work....i suggest you take some extra lessons after school to catch up. Ask a teacher for help, do your best to concentrate. Work somewhere where you can't get distracted. Think positively about all this, but something has to change! and you can do it! For your whole family's sake!
