I have been feeling very tired starting about two weeks ago. I'm 13 and a female and I weight about 125 lbs. I normally go to bed at 10pm and get up at 8am to go to school. Once im at school I feel tired through out the whole day and just don't feel up to doing work or socializing. Once I get home all I want to do is just sit around and watch tv or play computer games. I take vitamen D 10,000 everyday because I have low iron. I play a musical instrument as well and now well trying to play I feel a great loss of intrest. Lastly every night when I sleep, I keep constantly waking up and looking at the clock to see if it is a reasonable time to weak up (this starts at around 5am in the morning). Am I sick?????
