Am I too tired?

For ppl who know me, u guys know, I love to sleep, and love to eat. But ever since Sunday, I've been losing appetite on wutever I eat. Worse yet, I have not been able to get good sleep. I woke up about 5-6 times for each of the last two nights of sleep.

Am I really too tired?

or am I just getting weaker and weaker, and losing confidence on work in myself?
