Your weight: Is dangerously low. Discuss it in depth with your doctor soon, and even consider a psychiatrist for possible eating disorder.

Help: I agree with dr. Sneid. It makes sense that you feel continually fatigued with the need to sleep. Have you been assessed for an eating disorder, depression or underlying medical problem. Something is the cause.
