I would be more concerned with the amount of sleep you're getting or even able to get. Not many people can sleep that long. You may want to get yourself checked out, see if there isnt something physically wrong. Then you want to see if it is psychological. Depression or something of the sort.
Because you slept too long, to feel rested our bodies and minds need between 6-8 hours of sleep, when you sleep more than that, especially double in your case you will wake up feeling even more tired than before.
You appear to have missed out the entire first half of the answer. If you are sleeping that long, then there may be something PHYSICALLY wrong. Go get checked out.
