Thank you so much to everybody who replied to this

I did a lot of thinking about all of your posts. I also went back over some of the emails I've sent T over the past year (I kept a lot of them). I realized this man has incredible patience. He's been conducting mini-sessions via email with me almost weekly; I'm borderline, and some of the emotions that have come up would try the patience of a saint. It's a wonder he didn't reign me in before this. He's right - the work needs to be done face to face in the office, not via email, where so much can be misunderstood. And leaning on him like that every week was not teaching me to be independent, to regulate my emotions on my own.
I know that in my head - I just need my heart to understand. It will, eventually - right now I just feel a little bit abandoned. I know it's for the best, I really do, but I will miss that reassuring presence. Oh well, guess I had to put my big girl panties on eventually
Thanks so much everyone - love and hugs to all - take care
