The good news - nothing was broken - not my glasses, not my pda, not my nose.
The bad news - I have a nasty scrape on my nose, I bit my lip, my hands are scraped and bruised and my glasses need adjustment. And I got blood on my purse. All things considered, I got off extremely lightly, for which I am grateful.
I went home and cleaned up, and put a bandaid on my nose and got to work only a few minutes late (and that's with buying bandaids and antibiotic cream for the office, which something we need to have anyway.) I look not great, and I do have a bar mitzvah on Shabbos, but I will be fine. My hands hurt, though.
I think part of the problem was that I was wearing a backpack, something I don't do often, so my center of gravity was off.
