Increasing from once to twice (or more) per week?

No, I haven't considered it. I've been with my therapist for 1.5 years. He knows my story because he was there every week when things were escalating in my relationship. We have a good working relationship. Why would I give that up to start over with new people? We're managing the suicidal feelings but right now I need this level of support from him.

Insurance companies are so terrible. From this thread it seems like a lot of people benefit from therapy multiple times a week who don't need a higher level of care.

Ahhh, I thought I had decided about this but it turns out I'm still really torn! Or maybe both torn and decided

At my last session we found a time for a second weekly appointment starting soon, and talked about the possible impact of and reasoning behind increased frequency. Basically it's that he thinks adding another session would make therapy "two or three times as helpful," and might make it easier for me to talk more freely, as well as allow us to cover more material. That makes sense to me. Especially the idea of getting to cover more material, since focusing on the stuff about appointment frequency meant having to backburner some other things I want/need to talk about, and it never feels like there's enough time to talk about all of my top priorities.

But then I went to put the new second appointment on my calendar, and seeing it written out on all those weeks felt really nerve-wracking. That's a lot of therapy! Part of me wants to dive in, and part of me is still concerned that it will end up taking up too much time and energy and mental space, will make me too focused on myself in a selfish way, and could stir up more than I want to deal with right now. I guess we'll see.
