Hi BlankFace,
I'm sorry that your ending with your T has been such a struggle. It's so difficult to have a good working relationship and then to feel like that all falls apart, either over time, or quickly. And to have her not tell you that she was leaving - that just sounds cruel and unprofessional.
Working with another T might be a way to process what happened in this T relationship, though I can understand that that might not be the most appealing idea.
Feel free to come here to talk about it more. Folks here are pretty understanding.
