Hey... Don't beat yourself up about it... It is bow hunting... It happens. You made a valiant effort to recover the animal. By the sounds of it, he is probably ok... just sore.
Anyone who would call you a name for it is very ignorant. I don't know too many bowhunters who have ever recovered every animal they have hit.
Now you know and you'll be that much more careful about your next shot.
Don't beat yourself up about it too much.

Sorry you didn't get him though.. sounds like a real dandy +135".
