That seems very odd. Even if it were a termination email, it seems like the therapist would encourage you to come in and end things in person. Like others here, I don't know if this T is necessarily cut out for trauma work. I think some amount of warm fuzziness and some amount of outside contact can be crucial for helping people through trauma without leaving them to fall apart between sessions.

So I don't think you would be out of line to clarify that you weren't ending things with this T, but I do think moving on might be a good idea. I know it's tough to start over, but you need to be sure that you have a good companion for this journey.
