OK, I've known ppl before that fed only live rodents and could NOT handle their snakes either. I'd STILL advise having her stool sample checked for worms,
but I think you have to realize that she is now accustomed to doing battle with live rodents and the response you see is how she protects herself from injury.

Trust me when I say that if you want a pet snake to be relaxed and tame to handle, feeding live is just a bad idea, apart from all the risks...your snake has now
learned to stay in defense mode...it's nothing personal. If you persevere, you MIGHT be able to calm her down with "hook training" or other similar methods
that accomplish the same thing: letting her know for sure when food is coming and when she is safe. The best thing though is to do the "work" involved and
switch her to dead prey, either f/t or fresh-killed (f/k), because sooner or later, you'll be paying vet bills for her rodent-caused injuries, along with wishing you
had a real pet you could hold.
