Medical problems possibly?

Okay, so I'm wanting to know if there's something medically wrong with me or if it's just normal or it's just me overreacting?

Hhh, I have verrry frequent migraines.

And I mean, I almost ALWAYSSS have a migraine, and they last for days on end.

And I'm always soo dizzy.

Almost to the point of blacking out.

I'm always hot, when no one else in the room is. But I'm ALWAYS hot.

I can't ever sleep. I'm alwaysss tired.

And I don't get much sleep at all. Maybe like, 15 hours of sleep a week.

Give or take.

I can't eat food, or else I start puking.

I have severeee acid reflux, and mainly all I eat is junkfood because it doesn't make me sick.

And I have a stomache ache almost every other day.

But if you can tell me if what's wrong, or if I'm just overreacting or whatever, that'd be much appreciated(:

Thankssssssssss.
