me dx Oct 23 2012, age now 68.
to retire or to stay working... just a couple of thoughts - from my own experience I find the slightest stress brings on the judder in left hand. Proof of how fragile the body and mind is. I too have lost a lot of confidence.
I'm in different position to you in that I am retired but I am choosing to get rid of anything I dont need at home - clearing the decks and cupboards to enable me to really live as I choose and really to try to care for self. Motivation is sometimes hard to come by - but I do try to do as much exercise as possible and do try to meditate and spend time with those important to me.
Working full time you won't be able to do this so much. I feel that if financially one can step out of the work environment then there could be so many pluses - ime for self, time for exercise, time for physxiotherapy, time o enjoy walk amongst automn leavs.
Have just noted that your post was on 8th October - maybe you are closer to making your decisions?!
Go well and carefully
