Advice needed: what's a destitute hacker to do?

First of all I ask that anyone commenting please leave off criticism of how I got into the situation I did. Trust me, I've already thought over millions of times how I must be an idiot to have gotten into the situation I'm in, and if I could go back and make different decisions I would. But right now I'm not exactly in the best shape to handle criticism, and don't need to be convinced of anything. What I really need is advice for improving my situation, or any info about programs or employers, etc. that I don't know about. I never had a course in high school or college on how to deal with poverty, even though that might have been really helpful right about now.

I graduated from a state university in 2009 with a degree in Computer Science. I graduated with honors and a 3.81 gpa. My gpa could've been a lot higher, but I struggled with untreated clinical-level anxiety throughout school which lead to severe procrastination or simply not turning in certain projects. I got a 1520 on my SATs, was a National Merit Scholar and an IB (International Baccalaureate) graduate. Although I never went through with applying to grad school I got a 1480 on my GREs with a perfect quant score.

Now I'm aware that being a good test-taker doesn't entitle me to anything, and if anything I'm more aware than anyone else how test-taking skills or academic success don't really apply to real-life success. I currently clean houses for a living, and am barely scraping by on that. Recently I lost one of my clients for unforeseen reasons, and that put me back in a risky situation just as far as getting by. I can still pay bills and rent, but my food and gas budgets are really restricted. I'm basically eating beans and rice and not doing so well nutritionally, which has been especially apparent these past few weeks as I've had a cold that doesn't seem to be getting any better.

I am also without health insurance. May of last year was the last time I was employed at a job that provided health insurance, and after about 4 months my savings dwindled to where I couldn't afford to make COBRA payments anymore. This wouldn't be such an issue, but I also have anxiety issues that have gone untreated for a while, especially after I decided to cut back on taking some medication I was previously prescribed due to not being able to meet the monthly costs.

I held a programming job back in May, one that I had for 2 1/2 years before finally resigning. I worked at the University I graduated from helping with a research project. When I graduated in December 2008, most of the companies I had spend the past few months interviewing for had put a stop to their hiring programs, and the job I ended up taking was the only offer extended to me. This would have been fine, but over time and especially towards the end I had a great deal of trouble at that job. It would probably be unfair to call my boss emotionally abusive, but the lack of any praise, the high level of criticism, the lack of any process, the expectation of constant overtime, constant coworker turnover, left me extremely burnt out by the time I left that job. That was in May of 2011.

Besides the fact that my boss continually trash-talked on my predecessor, my boss was infuriated with me for resigning when I did (burn-out hit me really hard and I gave short notice after my productivity dropped and my sleeping habits and punctuality became erratic, and so I thought I was actually doing the responsible thing by resigning since I no longer felt competent).

So anyways with my last job since I left I've had a high level of anxiety that any new job I apply for I have basically had no positive supervisor references. Since I left my last job I have applied for a handful of positions, but with no positive results and a sense that grew over time that I was unemployable due to my mixed work history, and my increasing interval of unemployment (at least in tech). Thank goodness a close friend of mine showed me how to clean houses and passed along clients to me, or I might have been even more thoroughly convinced of how...
