It's hard to motivate yourself when depression takes hold. It really is. But, I have this theory...I don't know if it will work for you, but it does for me.
Even when I feel at my most bleak, my most hopeless, I still get up and do things anyway ("feel like shit but do it anyway" I call it). Let me give you an example.
Most days I like to go running, swimming or do weights. I have two choices. I can either sit at home doing nothing thinking bleak, dark thoughts...or I can go running, swimming or lift weights and think bleak, dark thoughts whilst I'm doing it. At least with the latter I'm doing something that has a positive outcome somewhere down the line.
Strangely enough, exercise does give you a lift. A natural high, if you like.
Anything's got to be worth a try.
