I have been experiencing mild nausea, flashes of dizziness, constant headaches, and fatigue/exhaustion for the past couple of days, and today I had diarrhea. I am in my early teens, and have been diagnosed with mild anxiety and depression, if that is an indicator of anything. I have been getting very little sleep lately (lots of homework, midterms very soon).
Is this just lack of sleep and depression mixing together? Or am I actually sick? What should I do about it? More sleep is out of the question if I don't want to fail half of my classes.
