I like depressedalaskan's suggestion of making a list, it could be a gentle reminder of the things that need done. The procrastination cycle can be hard to break but definitely go easy on yourself. Frustration with yourself could add to your depression.

Something that helped me when entering college is to give myself deadlines before assignments are actually due so that I wont wait till the last minute. Then once I accomplish my goals I reward myself by doing something I enjoy.
