There is the possibility that your medication has stopped being effective. Please let your doctor know what you have written here.

I also think that you're in a stressful situation -- university just is, even if one is doing well -- and you may react with these symptoms out of apprehension over the future. Start by telling your doctor and please consider counseling. If you are already in counseling, make sure you are sharing this. It could be that much of what you are feeling will ease up when you graduate, even though you don't think so right now. Hang on.
