Am I anorexic?

I'm really confused.
I think I might be anorexic...but not on purpose..does that make any sense?

I've got a couple of the symptoms..but I really have no idea whether it's anorexia or not.

I swore I'd never be worried with with my weight and I swore I'd never be anorexic for the reason of wanting to be skinny. I never realized I may be doing it without realizing it. I'm comfortable with my weight and I wouldn't mind gaining a few pounds or losing them either. I don't really pay attention to what I'm eating anyway. I usually make people call me fat..because I hate when people call me anorexic or skinny. I know..it's weird.

But...I've been really stressed out lately with school and my family and "friends"..and I haven't been eating much..or at all. Sometimes I skip out on breakfast or lunch or both somedays, without really meaning to. I just say I'm not that hungry...which isn't a lie, because usually I'm not.

Sometimes..I get extremely hungry and just eat because I'm bored. Other times, I don't want to eat at all. I've gone days without eating.

I've been waking up with massive headaches and my throat usually hurts. Sometimes at points in the day, I get dizzy. Also, I don't really sleep at night..the most hours of sleep I get is about..2-4ish. I think I am an insomniac.

But does that make me anorexic..just because sometimes I don't feel like eating?
or is that completely normal?
