Do you think i should go and see a doctor?

I found out about this a few months ago and I have read the symtoms of schizophrenia, and I have quite a few of them. I can go from really happy to pretty much the devil the next, for no reason what so ever! This happens about once a day, if not more! I...

get really dizzy sometimes, I feel like im going to fall over and faint. I sleep constantly, I go to bed about 10 and get up at about 7 for school, and when I get in I go straight to bed because I am SO tired, I wake up about 9 and then when I go to bed, I fall straight asleep again!! I've even fell asleep at school, and I always feel like im going to even if I dont. I feel really anti social all the time, I dont want to go out, just want to be by myself and just do nothing... These are some of the symtoms that I have.. do you think I should go and see a doctor about this or does anyone know what this could be? I am a teenager but im sure its not my hormones or nothing :S

Yep you definitely need to go see a doctor. You a missing some of the more key symptoms of schizophrenia. Which could be a good thing, I don't know of anyone who would actually like to have this disorder, but if you do only a good psychiatrist can help you. Good Luck
