Hang in there, buddy! Things will improve over time, I promise you. Like people, parrots go through a period of adolescence which can be quite trying at times, but they do grow through it eventually and settle down within a few years. Unfortunately a lot of people who are unaware of this end up selling their birds when they begin to act up and start biting uncontrollably. They can be taught gradually to stop biting, as long as it is done in a patient and loving manner. Getting mad and angry at the bird when it does bite will only make the matter worse. Birds bite for a reason most of the time. If you can narrow down the reason for its biting then you can begin to fix the problem. They can be very territorial and do not appreciate your intrusion into their territory. It`s best to find a place to get the bird in a neutral place, like a play stand away from its cage, to do training. When it does bite you just let the bird know that it is hurts and that it shouldn`t bite, but don`t yell and scream when you do this. Just say it with a firm voice that is commanding yet not overpowering. I would try using a stick or a perch to pick up the bird to move it in order to prevent it from trying to bite you. Good luck and don`t give up on the little guy. He/She is testing you to see if they can trust you.
