I'm glad you are still looking for answers to this. You deserve to know what's going on. Therapists have a responsibility to be honest like we do. I hope you get to the bottom of it and get your answers.
have you asked hm about calling? i never had a T i could call until the last one and that was so nice to know she was there if i needed her. this new T has the same set up: an answering machine and the recording says that if it is a life-threatening emergency to hang up and dial 911 of course; and that you can leave a message and she will call back; and that if it is an emergency you can call her cell. So I asked her yesterday to define emergency for me, because when I'm in a frantic episode I don't think I can do that. Basically she just said she leaves that up to the client and that if it is something that can wait till next session then we'll talk about it then and if a client calls too much or whatever that she would talk about that with them too. All said in her gentle, kind, reassuring way. .. So anyway, I wondered if you had asked about calling and when it would be ok. Sometimes we just need to get something out into the open or be heard and that can be a way to do it. I can see where it would not be something to make a habit of, since openness and emotional honesty are for the therapy session, but hey we aren't perfect are we. Wouldn't be there if we were.

We're learning.
