How COULD she respond?

Everything she may have thought may have seemed trite or if it angered her, which it well could have, how could she respond in that anger to such a heartfelt letter? Thus, silence.
I feel pretty certain she had mixed emotions but for you, I think the letter was a good thing and you did a good job. Those things you wrote aren't easy to realize about yourself and to actually admit it to someone that has hurt you takes mucho humility. Good work!

In closing, let's go with this:

Leave the worms alone and be sure to take good care of the people in your path from now on.
That's your lesson...
Don't leave things undone and unsaid.

That's how you turn your curses into blessings.
By being one.

Oh, okay dagnabbit...
Save a worm along the way, too, when ya can.
