Can't you explain all of this very rationally to your therapist? That you're out because you need to be out, she encouraged you to be out...and now she seems to be doing a one-eighty? If it helps, write it down in a letter and tinker with it so that you say exactly what you need to say in the way you need to say it. I would hate to see you start over again from scratch. Maybe your current therapist is salvageable, at least until you can get a T letter.
I see one positive thing about this possible delay: in your latest post, your position seems to have solidified. Are your doubts and second thoughts less tangible now? It does seem so. But then, that would be a double-edged sword if you might not get the T letter right away after all.
Hang tough, buddy. You'll get there.
