too much sleep, or not enough

I think I have sleeping sickness or something.  I've been waking up at noon.  And going to sleep at like... 11 or 12 at night.  (Who sleeps for twelve hours?!)  And then, when I wake up, I'm tired.  And I'm tired all day until I go to sleep and sleep for twelve hours.  This has been going on for four or five days.  I looked it up on the internet, and apparently I either have some sort of thyroid problem, or I'm clinicly depressed.  I vote the latter, but it's lurking around in my subconcious if anything, because I thought I was having a good week.  I have good books, been spending a lot of time outside by myself.  Think I might go out rollerblading again--and when I go rollerblading I smile like my face is going to break in half, but when I get home I'm tired again and have to take a nap.

Am I not eating enough?  Or the right things?  Or do I need counseling. ._.

School soon.  Counseling is free there.  But I don't think they'll be able to help me with eating right.
