Once again, this is extremely helpful, Mark. Thank you. I'll look into all of your suggestions.

My work situation is a bit odd, since I'm still a grad student. I've been able to keep my funding assignments, but only because the past couple of them have involved very little work. I lose my funding (and my health insurance) as of June, and will be in no position to work full time. In other words, I've been able to stay employed so far, but only because my funding assignment for last fall and this spring is and editing assistantship in which I only do about 5-10 hours of work a week. It pays less than $1000/month, but also comes with a tuition waiver, and the course I taught the previous spring paid more than that. I was able to teach that course because I didn't have the light problems then (it was before my relapse) and had taught the same course twice before.
