I think this is what I used to feel like. I had some energy today, enough to complete ten solid hours of work and still grocery shop without forcing myself to do so. My legs hurt, but I could walk up and down stairs without hissing in pain and clutching at the railing. It was very weird.

Over the past six months I've gotten used to the status quo, but some corner of my mind still has some hope that things can get better. If I'm lucky I'll have more days like this.
