Hi, I m 13 years old. Im a girl, too. I ve been having severe headaches for the past year and a half. Recently, I ve been having loss of appitite, a really sore throat, random pains all over my body, and a sore back. For about 2 months, I ve been waking up about 4 to 5 times a night. I only get about 4 hours of sleep due to this fator. I ve been randomly gaining 5 pounds, then I ll lose about 7 pounds, by duing nothing. I ve been having sore muscles by my shoulder blades to. I m about 150lbs. I m a really active person. I want to know whats wrong with me before august, so im ok for volleyball season. Also, I get strech markes on my inner legs, I m just wondering, how do I get them if I m not fat? And, how do I get rid of them. And, I ve been really dizzy for about 3 weeks, and it s so bad, that I ve been falling down, even at school! Please help me!!!!!!
