I almost never exercise, but if I did, I know it would improve my energy and concentration, as well as make me more physically fit and possibly more attractive. Running, or working out, or doing some sport is probably a great way to fight depression and maybe work up some energy for other activities, including improving your self-confidence. You don't want to sink into a cycle of apathy, believe me.
If you can convince yourself to exercise for an hour, and once you start it'll be easier and you'll probably enjoy it, you're well on your way to being able to convince yourself to do other things.
