I see two realistic options... Feed her live or assist feed her.

Both have their downsides, but either way your snake will get a meal in her.

Try to look at it this way, What is worse to have...

A snake that could get bitten by its meal, but is eating.
A snake that is stressed out because you had to assist feed it, but is eating.
Or, a snake that is starving its self to death.
