Do get the lumps and bumps checked out. If they are negative, then go to a psychiatrist. Your symptoms sound a lot like anxiety to me, especially since you are a college student. This is very stressful for some and the weight loss and chest pains and shortness of breath as well as throat pain are all symptoms of stress and anxiety.

Good luck
