Hi Monique - I agree with Barb! Don't give up. Like she said, if you have to take a lighter load for awhile then do it. I am also a professor who is newly diagnosed (Sept. 2007). I worry about the future and whether I can keep teaching but I am soldiering on. Don't ever believe that getting your masters degrees is a waste of time! Even if you don't wind up "using them" in the future (and there is no guarantee that will happen--what happens if you never have to apply for SSDI?) they will still have value. You will have worked very hard for those degrees in spite of the odds and raising a family and that is to be commended. It also sounds like you like to learn and challenge yourself aside from just getting the degree for professional reasons. So keep going even if you have to slow down.
Good luck with everything!
Natalie
