we have a lot in common. My name is also Jeff. And I totaled my beloved ST1300 on June 1, 2011 - a date that shall forever live in infamy, at least for me.
Don't be too hard on yourself. You were smart to wear the gear, but as you can see, it will not prevent bruises or broken bones. You made one bad decision in the heat of the moment. I did too, we all do sometimes. It's just that most of the time we get away with it.
It will probably be a life changing event for you. You start to realize what is important, and what isn't. You start to see the potential cost of your decisions.
Get back on a bike, asap. I didn't replace the ST for almost a year, but as soon as I was physically able, I rented a bike just to make myself get back in the saddle. These days I am riding a Kawasaki Nomad, and loving life in the slow lane.
