Thumper...I'm sorry and glad for you at the same time. All of us with a diagnosis have been there...it is a relief and that very uncertainty of the future all in one.
I remember when my neuro at the time told me...then he said, you will probably be in a wheelchair within x amount of years. I said, not without kicking, clawing, screaming and digging in with both heels. I've stuck to that...yes, my MS has gotten worse over time, but I still do walk...not as sexy or elegantly as I once did. lol
Oh yeah and the kicking clawing thing...I've been doing that since the age of two.
I thought of it this way...getting the dx did not make a difference in what I was feeling or how I felt. I had two choices to accept it and live my life or give up...I accepted it, I live my life the best I can on any given day...and I'm thankful for each day.
Some days I do remember things I once did that has nothing to do with the age I am now...its the MS saying...your brain says ok, lets do this...but the body says...oh yeah silly, watch me do this!! lol
