Kick her out of your bed! No note, just lock the door. Does she have a key? Make no bones about it, she is out as long as she continues this disrespctful behavior.
Period!
As for the depession part, yes, it is part o the process. The mornings are the worst for me as well. Inertia is linked with depression, force yourself to get our of bed, take a shower, brush the teeth, put on the makeup and get moving. Go anywhere there is a wi-fi connection and do your work there - public library, starbucks, college library, Panera's anywhere.
