Everyday it seems to be a fight to get out of bed. I too sleep horribly at night and tend to wake up several times. I wake up feeling exhausted and never well rested.
Depression stinks like that. It can make us feel lethargic and tired all the time. It can take a lot of effort to want to motivate ourselves to get up and move.
If I really feel as though I am feeling crappy I usually allow myself a little extra time in bed, even if it is just cuddling and not sleeping. Sooner or later though I tell myself. "Get up you cannot stay here forever."
Do you have a therapist? This should be something you should talk to him/her about.

Stay strong,
