From reading your updates, it sounds like your boundaries are being violated by both T's!

We may not have the entire story about why you no-showed with your first T, why your first T terminated abruptly and with a referral (which might only continue the issues you had with the first T if both T's are in the same network and under similar guidelines), why your new T will not see your struggle with all this and suggest revoking the meeting due to your distress, and what possible benefit an old T that NEVER SAW YOU could possibly offer anything substantial to the new T without having even met or evaluated you (that would be unethical itself).

These are all RED FLAGS in not only the T, but the institution for which these T's work for or are trained by or are licensed by. If the T's are still under training and supervision, then they are NOT seasoned and likely to make mistakes, including ethical ones, depending on where you reside. If you're in the US, then this entire situation calls for a red flag!

It sounds as though your first T is making assumptions on you being a danger to yourself and/or others, without having even seen you in person. It also sounds like your first T is handling things wrong, is scared of you, is trying to warn your new T about something your old T doesn't even know for sure, and has unresolved issues based on the way this case is being handled.

Most are afraid not so much of you, but rather of being sued or reported to Boards, OIG, etc.

Then there's the misdiagnoses that can ensue when you're merely asserting your rights to receive fair, ethical, and non-discriminatory treatment. They may see you as "resistant" at the start, and some may infer that is indicative of some sort of conduct disorder or personality disorder, without having fully assessed you.

If I were you, I'd chuck both T's after all this, explain how you've felt distressed from both of them conversing without you, how you feel misunderstood, how a diagnosis or discussion of concerns about you without having even met you appears unethical to you, and how this entire scenario is unhealthy and unethical for your needs as a client. I'd basically revoke their communication and move on to a completely different institution where you can receive proper treatment and start over. Both T's are RED FLAGS! In no way will you receive the treatment you deserve, even if both T's never speak; the scenario now would be your new T would question you about why this took place, and it's too late now to start over with a new and open-minded impression from your first T.

T's are human, so their biases can easily enter the therapy room.

Can you find a new T and a new place where none of your old T's know one another? That's the safest best for you and your treatment needs.
