@Pain567567,
I have been there too. I was trying to re-enter the technology industry after the dot com bubble burst. I was out of work for about 18 months. It is very frustrating... but things do turn around.
The most important thing; you have to protect your mental health. Obviously the more upset and stressed out you are, the harder it will be to find a job. You need to figure out a way to break this cycle. Jespah has some good suggestions.
I found networking groups with fellow job seekers to be fairly helpful. We also formed a smaller support group of just 4 or 5 of us who talked almost daily. We held each other accountable and tried to keep each other focused.
There is also common advice; I find it helpful. Make your job search be your job. Set a job search plan with daily tasks (these can be from researching a company, to networking to making calls) to volunteering. Give yourself 8 hours of work, 5 days a week. If you are doing this, then no one has any right to pressure you.
My unemployment ended very strangely. I went to interview for a paying software job with a non-profit organization. It was a weird interview... two very smart people talking about me (occasionally asking me questions) rather than talking with me. Finally the president turned to me and said "you aren't qualified for this position".
I answered, "I like your organization and I think I can do good work here... I would like to volunteer my time while I am looking for work". I figured this would be a way for me to get some experience and some good references. The president then said "No, we will want to pay you". Then he offered me a paying job... right after telling me I wasn't qualified. Go figure.
You have to keep trying things... and make sure you don't lose hope... until something works.
