Some things to consider, first get a rack for the rear of your commuting bike(s) and some saddle bags to carry things in. Riding with a back pack can easily get your back broken as I saw with a member of the old club named San Diego Wheelmen on a return from a trip to Tijuana for tacos! He slid on gravel and went down and when he tried to get up his legs had no feeling!

Second you should have called 911 and taken an ambulance ride to the ER so they could do x-rays as needed and more importantly scrub out the dirt from all the road rash areas! I had a bad crash at a race in Lemon Grove in 1979 or so and had some bad road rash on my right arm, right leg and right hip. The doctor said it has to be scrubbed and disinfected as there could be some really nasty infection causing stuff in the wounds! Dammmmmmmm it sure hurt!

Third is going hard or fast right away and not looking 300 yards or so ahead for hazards.

Fourth is I hope you were wearing a helmet as you didn't mention it so if not then get one.
