My friend with MS is the bravest man I have ever known. Mark, this is for you!

I can't explain the feeling
the pain of being me
I am still the man that I used to be
In my mind I run, jump and
every time ,I make the basket
But this body has betrayed me
It just can't do what I ask it
I am now a prisoner locked within my mind
I am looked upon with pity,
If they look at me at all
Don't cry for me, but don't look away
There is so much I have to say
Fight the fight, it is worth-while
and as "they" say, remember
"There but for the Grace of God"
the rest, best left unsaid
