Crazy chick hacked e mail blocked me now using my e mail to destroy me how do I stop this

Change your password. If she changed it then request a change and have the info sent to an alternate email address. If you can't do that then contact the email provider asking for the password change. And explain the situation.

Pick better pass words, it appears she knows you well enough to figure out words you may use, So go in and change any and every pass word you use
