People here have been giveing some good advice, you and your mom need to have a seirous talk. Try to work out something, explain that you are becoming a man and if you are keeping up your grades, she shouldn't *****. Also lay it out to her that if you sell the truck and have to move out, you'll have to QUIT SCHOOL and work more in order to survive, because of high cost of liveing. Try to stay calm and cool while explaining things, go by the rules of her house but tell her that she will not control your life, and things like this can make LONG lasting problems in your relationship and you don't want this. Hope yall can work out something, good luck and God Bless You.
