Good luck. I hope you find something so you can support yourself. Even if it requires less skill and training, and pays less. But keep applying.
Or, stay where you are (are you living with your parents?), get a job, any job, just to save money, then apply in other cities where there are more jobs in your field, and move and start over there.
I finished graduate school with an MS in math yet no experience and little money. I spent all of the summer of '98 applying and interviewing with no success, even though I had a good school record, and a degree. I finally got two job offers in August. I had about $1000 left to my name, plus a credit card, so I was getting desperate. I took one of the offers, and have been there ever since.
Once you get started, and get your foot in the door, and a few years experience, it will get easier, not just to be promoted, but to move to other things elsewhere. Where I work, people usually leave after a couple years. Those that stay more than 5 or so years tend to stay for the duration, or at least stay in the organization, but perhaps move to another office within it. Some move up the ladder.
I am closer to retirement now than to my date of hire, and people retire which opens things up. But I have not yet gotten ambitious, not yet sought those positions higher up which pay more, mostly because they require more responsibility and for me to deal with more people. I am best working alone.
Good luck again.
