Larry, I don't know you well, and we have never met in person, but I think I do know you enough to know that traditional archery does mean quite a bit to you. And I can understand how after hearing that report from the doctor you may be disheartened. It hurts to hear that you might have to give up something you love.
But just like in relationships, it is worth fighting to save something you love. Even if it means that things won't be quite the same as they once were.
I would encourage you to listen to some of the advice above from people that have experienced what you are going through. Maybe some of those things can help. Maybe it means a much lower draw weight. Dick in Seattle is passionate about this sport even though pysically he is limited to very light bows. As has been suggested, try a release. Not a thing wrong with that.
If nothing else, just lay the bow down for awhile and come back to it whenever you are ready. And in the meantime, stick around here. These are still your friends, and you don't have to shoot a bow to log on here daily. You have much to contribute even if you are not shooting on a daily basis.
Good luck, I'm hoping you find an answer that makes you happier than giving it all up.
