Sorry to hear of your horrible crash.
I took a fall a few years ago and fractured by shoulder, not half as bad as what happened to you. I was in a sling for 6 weeks.
Although as much as it was scary I always planned on getting back on the bike. When my shoulder was better I began riding my mtn bike through my developement and eventually went on my road bike. Although my fall was caused by broken up road, it made me a more cautious rider.
I hope you heal quickly and that you eventually enjoy riding again, it may just be with a different frame of mind.
