I think the best thing is to really cut the ties, don't email her, don't try to get her back. Because in all honesty on your part - how sure are you that you are not trying to get her back because of your feelings for her? The reason right now is that you miss her - and that's understandable, you think you are in love with her.
But for your actual issues and your own well-being, it's best to work through all this with a new therapist.
I can actually understand why she terminated you - and you understand as well. Therapists have to protect themselves as well and your history with her sounds like a really complicated one and one that had a few heavy, heavy incidents. She may feel that she really can't work with you and as hard as that is for you, you will have no choice but to accept it..
