Go see a doctor. If you're broke, check into social services. You might qualify for some sort of medical assistance. Even if you have to pay some money, do it anyways, it's your health and you need to take care of it.
Also, keep looking for a job. This is the worst economy I've ever seen, but there are still jobs to be had out there, just don't give up.
"Of all tyrannies, a tyranny exercised for the good of its victims may be the most oppressive. It may be better to live under robber barons than under omnipotent moral busybodies. The robber baron's cruelty may sometimes sleep, his cupidity may at some point be satiated; but those who torment us for our own good will torment us without end, for they do so with the approval of their own conscience." -- C. S. Lewis
