Go to the doctor, you could have Mono (You sleep alot trust me and your spleen is enlarged and if untreated can rupture with over exertion), a thyroid problem, or several other things that only a doctor can help you with.

Sone other questions are, do you have a sore throat? Tenderness in any parts of your body? Feel like you have the flu? Are your lymph nodes swollen (Your neck and underarms are the most common ones)?
