Ahh Marion, I'm sorry.

Gee I never thought of myself as a "good sport" but more like a
"bitter curmudgeon" whilst living through 50 years of this @%&*ing
disease.

Shortly after my DH passed away in 2004 and left me to live alone,
I decided to use a scooter in the house and outside, rather than fall,
ungracefully to the floor, after tripping over a piece of lint. Didn't use
it, so lost it.

If you want to keep walking, then you have to keep walking. Your
Doc writing a script for some PT, may help. Aging is not our friend
though, so no matter what you do to keep yourself strong, we get
weaker as we age + MS = forgettaboutit!

Good luck and good wishes for you.
