First of all, congratulations on achieving the level of education you have, given your self-assessment of having been depressed for most of your life. Psychiatrists would consider that to be clinical depression, which is a chemical imbalance in the brain--thus the need for medication. I'm not a big fan of antidepressants myself, but some people I know absolutely need them. I think you need to be open minded about all possible remedies for feeling better.
I also wonder if you are at all in touch with your feelings beyond sadness. Your posts make it obvious that you are a very intelligent person. Perhaps too smart for your own good. While you rationalize and dismiss suggestions, you really give no indication of FEELING. A good psychiatrist will be able to "press your buttons" in order to evoke a gut-level response. I think this would be more helpful to you than intellectual sparring.
Regarding the job situation, everyone that is out of work is finding it extremely difficult to find a job--any job--regardless of education. It's simply the way things are right now. Perhaps you could consider teaching, though that will require some education credits. Adult education classes will hire based more on job experience in a certain field than education creditentials.
Please try to keep an open mind to all possibilities. I hope you will soon find a doctor you can trust to help you.
