What headache is this please help?

Breathe. Sadly the stress your experiencing is just a glimpse of what adulthood is going to be like. But you get thru it by learning to take things one pace at time. Headaches like these could be a number things: ear infection, malnutrition, not enough water, deficiencies of numerous stuff... But a doctor visit would help. Also, even if ends up being cancer (which I'm not saying to joke) nothing is set in stone. You might be working yourself up and adding stress. If nothing is found with the doctor's visit, then perhaps try visiting an acupuncturist who can stick needles and give you herbs. Relax.
