Sheesh! What a good run of bad luck!

You're injured enough, so don't beat yourself up too much over the sidewalk crossing. It may be illegal where you are, and maybe it wasn't the safest possible thing, but it's hardly an unforgivable sin. In my area it's perfectly legal to ride your bike across a crosswalk so long as you enter that crosswalk at a walking pace. That women may have hit you even if you had dismounted to cross; we'll never know.

Hope you heal up quickly.
