Hello techman: Well... I don't know as there is much of anything I can offer here. I simply wanted to leave a reply letting you know I read your post & I wish you well.
It is going to be important for you to find some kind of job you can stick with. All of this job-quitting is going to come back to bite you at some point. I don't know if you're looking specifically at tech jobs. Perhaps given your temperament tech jobs, at least the ones you can qualify for at this point, simply aren't the best choice for you now.

Just a thought. The important thing here is going to be to find something you can stick with so that you can begin to develop a consistent work history. Good luck with your job search!
