I'm so sorry. I feel so upset for you and angry on your behalf that she told you those things and gained your trust (possibly well intentioned at the time) only to end things abruptly in an email. I'm not surprised you're in so much pain. I echo what Beth said that it's so unethical and something needs to change. I know I speak of therapy positively but I absolutely appreciate the emotional damage it can cause too and I'm just so sorry you're having to face this. It should never have happened and your ex therapist should be accountable for this.
