Yeah Sally!!! Glad you are feeling better today.
On Sally's note . . . I sometimes think of myself as that gerbil on the wheel. I get on the wheel and start going and going and then stumble, get stunned by that blow, then get so ticked off I get back on that wheel and push harder. I am a fighter. With MS, that's not really the best because then I push/fight too hard and stumble even harder.
Of course, then I have to switch the image to a fun house wheel (that gerbil wheel squeaks too much

) and giggle to myself as I stumble around in the fun house wheel. There is humor in some of this and I really try to see it.
