hc's point is a good one.
One of the major issues with clinical depression is bad sleep patterns - either sleep is absent, or if present, it is not restful, plagued by vivid dreams, and generally disturbed.
I have suffered from depression for a long time, and even though i am balanced by medication, i find waking difficult. I have to reassure myself that my nightmares (which are constant) were just that, and then i check my mental equilibrium as I stand up and head for the bathroom.
As a non-morning person, it takes me a while to fully wake and function properly, and i remember from my seriously ill days that such feelings would often psuh me into feeling that my lethargic and wooly-headed state were there to stay.
It is harder than ever to find any motivation, but treat yourself gently, and allow yourself to come round slowly and softly, and then see if you are able to do something - anything - to get your day started.
