Yea, it really is depression related read up on it. Something is bothering you and causing you to oversleep, the thing is, it's not even comfortable sleep. I remember the doctor put me on a "rem" machine or some shyt to check my sleep patterns, and I was never in a complete sleep phase, so I was always mopey/tired/exhausted. You did say you broke up with your girl recently or some shyt, go get it checked out homey.
