Firstly, glad to hear you are on the mend. Trust me, I know what you are going through and the good news is that you will bounce back and probably sooner than you think. Just don't rush it.
Take away the road rash and concussion and add a broken leg and those were my injuries EXACTLY from the spill I took last month: Grade two laceration of the spleen, ribs 2 through 7 with multiple fractures, shoulder blade fractured in two places and a fractured fibula. Luckily for me I was in in full gear and got only one small spot of road rash on my knee. Oh, and not a single bruise, if you can believe that.
Similar too is your consideration regarding putting an end to riding. My wife and family are tired of these close calls as well. Someone on the rider board here suggested getting a roadster, like a Miata or a Boxter, so I have been looking into that. Something you might want to consider too. Just a suggestion.
I trust you got to keep your spleen? I did but it was touch and go for a while.
The ribs will take a while and your shoulder blade, depending on where and how badly it was fractured shouldn't be too much of a problem.
I crashed July 19th and by August 18th I was good to go back to work - I didn't but I could have. LOL.
Take care.
