I'm curious - did you sign a release for each of them allowing them to discuss you? If they did not EACH get a signed release, that is a huge problem.

But also - I would be hugely distressed if my current T talked to my former T. Can you get a session asap so you can talk to your T and have your nerves calmed a bit? That might help. Otherwise, as hard as it is, try not to obsess over it at this point.
