Can anyone try to tell me what I might be suffering from?

From my perspective it seems like you've got some really, really bad paranoia, and there is no problem, you are just worrying yourself into thinking there is. Does your family have a history of mental disorder or drug addiction, and are you addicted or on any medications right now? Have you even talked to your mom or anybody about this? It seems to me you get migraines. Please talk to your mom or a parent about this and have them take you to the doctor. Get to the doctor and tell him your problems and they will be able to help you and run tests on you.
