Hi Annie,
I know exactly what you are going through! I am a work-aholic by nature myself and wouldn't dream of going on disability. (I was on short-term disability for 3 months and I was going crazy!) I am also putting on weight and dealing with other consequences as a result of my RSD.
However, being on STD taught me a few things. Stress definatly made my RSD worse. I am now back at work at a nearly stress free job, though I am working more hours each day. My RSD isn't nearly as bad as it was when I was in a more stressful position in a stressful environment. I know you don't wish to change jobs, but I don't think working that many hours is doing you any favors. If you still received a slightly negative review, then I wonder if working those extra hours are paying off...?
I agree with Kara - I've heard good things about the software you can speak to and it will type for you. What about getting an assistant? I'm sure there are a few Grad students who would be willing to work with you, which would hopefully reduce some of your stress.
Is there a disability resource center at the university? I believe most schools have a center where students with both physical and learning disabilities can get help - maybe they could point you in the right direction? Do you work with any other people with disabilities? Are their needs being tended to? Is there a secretary you could "share" with someone else who is also overworked?
Good luck!
Best,
Meri
