Sleeping & Eating is it normal

For about two months my sleeping schedule is out of whack. I wake up at 2 or 3 am, then fall back asleep. Last week I would wake up at 5 am. Now I'm just not sleeping period. Since I can remember I've always loved eating, I love eating good. I'm a graduating senior & throughout high school I've been an athlete along with my misconstrued sleeping habits, I've lost my appetite completely. I just don't feel like eating, I can feel hungry but I won't eat because I just simply don't feel like it. Am I okay ? Is this normal?
