What happened was wrong, wrong, wrong. It was probably a good idea that the T decided that she couldn't cope anymore but the way she went around it was just plainly wrong. I wouldn't push for answers there is really no point. Your T did have an ethical obligation to find/refer you to a new T and support you until that happened. From the sounds of it you had a stormy relationship with the T so it probably worked out for your best interest in the long run. Find a new T that better suits you.

Good luck and don't give up!
