I'm so sorry you're going through this. I've also been comforted by my T like that, and I'd feel absolutely crushed and rejected if she suddenly started withholding touch. And I think it seems even worse that she alerted you to this change via email.

I'd think that, if T is going to suggest a major change like this, for YOUR benefit, she should discuss it with you and see how you feel about it, before deciding that she knows what's best for you. That's my feeling about it. You know yourself better than anyone.

Did she seem receptive to hearing how you're feeling about this change in her behavior?
