Hi Sally
No words, just a HUGE

. I think you have just put into words what so many of us fear for the future.
Be gentle with yourself - a good friend of mine who has made it to 86 years of age (and has had MS since her mid-thirties) said to me that she looks for beauty every single day - in nature, and in people - and that is what keeps her going despite all her challenges.
