How can I get my motivation back?

I broke my foot on the job a few months back, and was out of work for a month. After the injury healed, I decided not to go back to this job for different reasons. I've got a great job opportunity, but it's a county job and they're in a hiring freeze, so it'll be a while before it comes up.

I've had absolutely no luck finding work of any kind, I've tried everything I can think of. I feel so discouraged. I'm depressed, and I feel like I have no motivation at all. I don't feel like exercising, going out or being with friends and family, and I've even lost my desire to be involved at church. What can I do to get out of this "funk" that I'm in?
