Nothing makes me happy any more...?

I don't talk to many people, my house is very isolated, I moved away from my small group of friends to pursue my career and got seriously ill, I lost my job and can't find another, I feel like a total utter failure. I've stopped going out and having fun due to needing to save money. But I'm thinking that I just don't care about that any more. But spending lots of money will also make depressed. What can I do? I feel like I'm wasting away!! Like I'm going to look back on these years as the worst of my life. Where can I go to meet people?? What should I do?
