A couple of things....did you hear that your former T was saying mean and unflattering things from a reliable source?

Anytime I hear something from someone else, I try to consider the source and understand what is motivating the source to tell me something they know will hurt me. I understand it's hard to hear that someone you trusted would betray you like that, but if someone "heard" something negative being said about you, why would they share that with you knowing it would hurt you?

I like the idea of writing a letter, but maybe hang onto it for a bit before mailing.....

Sometimes when things are really causing painful emotions, we take action (like mailing a letter) that we later regret.

In terms of trusting a new T, all I can say about that is that I have had some really horrible T's and some amazing T's in my life, each time it's a new process to form that connection and trust. It might take a couple tries, but you will be able to find a T you are comfortable with.

Hope this is helpful....just my thoughts...
