I'm worried for my future. PLEASE HELP :(?

well first. you"re not your cousin and that's that. secondly if you know you are acting badly, then stop acting badly. YOU are in charge of your behavior thirdly some people work with their hands and that sorta thing is just better for them "school learning" isn't for everyone. if it were we wouldn't have a single mechanic or farmer. but we gotta have cars that run and food to eat. you do need to work out why you arent get the marks if you "have it in you" and you need to work on why you"re fighting. see if someone can give you one of those tests that "read" your answers and give you information on what you would probably be good at. maybe your school counsler can tell you where to get a test, dont know if they are online or not.
