Recently I've been having horrible headaches that would ruin my whole day and just made me want to sleep when I get home. I also have upset stomach with it too, I can't eat a lot but I will always feel like I need to throw up. Also im always tired and some nights I sleep for 12 hours and still feel tired, other nights I can't sleep at all and wake up feeling sick. I haven't thrown up, im 16 and im definitely not pregnant! I don't know what to do but I am very worried for my health
