So, what Tay said, that my T isn't going to go for my new plan, just won't get out of my head. I'm trying really really really hard to not contact T, so I'm trying to avoid asking her even though I would really like to just call or text her and do just that.

Anyway. It might help me to keep talking about it here instead. Here's the situation, in case I wasn't super clear about it yesterday.
I have plan with T to see her on a gradually reduced capacity for the next 9 months.

I have, all along, had a case manager through the agency that oversees mental health in my county. This agency has contracted with my T, who is not in my county, to provide DBT services and they pay her directly. That's how it's always been. I've seen my case manager 1-4 times a month during the 3 years I've been in DBT.

I had one case manager at first, and she left so I got another one. Now the first one is back in this county, and she has agreed to be my case manager again and to provide therapy once I'm done with DBT. I met with my current case manager yesterday and she said that her supervisor thinks it's a good idea, and that they will continue to pay for DBT until I'm done. Everyone there seems to think it'd be good to see my new/old case manager, in her capacity as a supportive therapist, during the transition (and afterwards, obviously). She is not a DBT therapist and will not be doing DBT with me, although she does have some training and she knows the skills.

The question that Tay brought up is whether this is going to be a problem for my current T. Let's just call her DBT-T for the sake of clarity. Like I said above, I'm trying to avoid contacting DBT-T, but now I am full of doubts and questions. Is she going to say no, that's not ok, you have to stop seeing me or wait to see her until you are done here? Is she going to go along with it because it is clearly what is best for me? Is this just another sign that what I need, and what DBT-T is avoiding, is a clean break from her?

I'm really confused, and really really struggling because I want to just ask her and at the same time I want very much to not ask her.
