Just because I had that accident and my knees are swollen and my arm in significant pain from wrenching it badly, I did cancel my appointment. However, they did not ask if I wanted to reschedule. :/

I keep thinking to myself that maybe if I get down the stairs again one more time, I might never have to go back up. It's just wishful thinking. But I really did myself in with that accident. Now instead of being a phase that can end, it's a full blown panic that will last to the end of time. I don't know wtf to do other than see if someone would follow me up the stairs.
