When you really don't feel like doing something, do it anyway. The motivation or urge to work, play, craft or whatever it is you would like to feel like doing may not appear while you are depressed. But don't miss out on the daily activities of your life, the big and the small, because the motivation isn't there. Jump in and get started when you can. At the end of the day you will feel better having accomplished something. Depression may rob you of motivation; don't let it rob you of your life.
