I don't know your lifestyle but as young as you are, you shouldn'thave the problems you do. I read a post in the health section you made about other issues. All i can say is excersise&eat healthy. When i was your age i rode bikes everywhere, played plenty of sports and stayed active, all while being high. Even last week i went for a 22mi bike ride w/ a pocket ful of blunts for the trip. Its all about excersise & good food.
