Well, what I can say is, some people just aren't worth your trouble, and you gotta make up your mind.
Either A) You want to mend the rift between you two
or B) You never want to hear from her again.
If you pick B, block her email and don't even bother with her again. She's not worth your time and all she'll do is be a jackass, so best not to feed the attention-whoring troll.
If you pick A, good luck with that. It's a pain in the ass and she might ignore all your efforts anyway and just keep taking stuff out on you for no reason. And the worst part is she'll think it's 100% OK for her to do that to you, even if she'd hate for you to do that to her. I've had some experience with her kind (not as exes, mind you; I just deal with enough of them every day of my life that it should count for something. Also, some of my friends have exes of the sort) and I can tell you that if she's as bad as you make her sound, you're not going to get anywhere until she grows a brain.
Whichever you chose, best of luck to you.

And it's as a wise man sang:
"I'm believin' too much in all the stuff in my head
It's a hassle in the mornin' to get up outta bed
I'm holding on to secrets that are too hard to see
And I'm thinking everybody is a-better than me.
I try to keep doing what I think I gotta do
If I make a mistake you're gonna think I'm a fool
I'm always back again to the point where I began
I'm afraid I need help - don't offer your hand
I know, you know, they know, we know
I don't know nothin' but I gotta keep bluffin'
I'm thinkin', they're thinkin', you're thinkin' I'll drink
Feel so confused that I think I wanna sink
It's so hard to talk when you're walking in shock
It's so hard to see when you're pretending you're free
Don't know how to give, and I've had all I can take
Everybody's to blame, when you can't play the game
I've been namin' and a-gamin' and a-framin' and a-blamin'
It's a pattern I've been weaving for a long long time
It's hard to begin, but surrender means win
And it certainly is better than losing your mind
I know that you've been thinkin' I've been talkin' 'bout me,
I made it that way for a purpose you see
Scatman's really only tryin' to get through
To help you discover he be talkin' 'bout you
The things that hold me back are right here in my head
The saboteur, he can't endure, he has to go to bed
I wanna live illogically in spite of what I think
I think that my opinion should be thrown in the sink
I wanna do better, but I don't know how
But if I'm gonna start I better start right now
I try to survive and I gotta let you know
If I'm gonna live at all I gotta gotta let go"
