I have been sleeping too much in a day for the last two years and I seem to have lost interest to do anything at all. I feel tired all the time and at first I thought it was because I was just lazy or something but I even tried working out everyday, I still do but it hasn't changed anything for me. I need to know what the issue is. I sleep too much, I'm not interested to do anything, I feel hungry all the time, I'm very cranky and on the edge most of the time. Is this clinical depression or anything else that I should be paying attention to?
