Hi Firedude17, Welcome to the forum. School is very stressfull and you are also at a age where you are getting ready to transition into adulthood ( getting ready to make some big life decisions ). All this has probably been building up in your mind and coming out as physical side affects. Your thinking about your grades and a girlfriend and probably what your going to do with your life etc, etc. This is really tough stuff and stressfull to. This all leads to anxiety and stress and the physical symptoms you have mentioned. You sound like you have been checked over by the doctors pretty well so hopefully you can rule that out. Take some time and look through the forum and check it out. Never hesitate to ask a question, we will be here.
