I'm tired all the time why?

I'm tired all the time. And sleep a ton. But why? Is it because I hardly ever eat anything?

It's not depression.

I'm not anorexic either or else I'd be really skinny, I'm fat but I just don't eat for days at a time, and if I do eat it's something really small and fills me up. My whole appetite got thrown off when I got the flu back 3 months ago.
