How do I get out of this

I would like to know what I can do to (at least mentally) get out of this situation? I am depressed because of my living, financial, and social situations. I don't really have a way to deal with this so I work until I am blue in the face, worry about my finances until I know where every dollar has gone, and stay away from fun social situations with other people. This leads me to have a incredibly bleak life style. All work and no play make me a dull person. How can I get out and have some fun in cheap ways with other people so I don't spend my weekends sleeping and my weekdays working until the sun goes down? Thanks
