Today, reality set in.

Oh, I walked some more, but my legs felt wobbly and after yesterday's adrenaline rush, I realize just how far I've got to go. I think I surprised my therapists with how far I was able to walk and that's always a fun feeling.

But sitting on an exercise bike, it is obvious how much things have changed since the days I would walk 5 or 6 miles in about an hour.

Will those days ever return?

I don't know.
