Have you been tested for diabetes? I have the same symptoms and I am 14, but I have also been excessively thirsty and having stomach pains. My parents are having me go to the hospital because the symptoms have been getting worse. It also could be IBS and stress. That can do that to you. Go to the doctors and make sure you don't have any severe problems. Good luck and hope you feel better.
