Have you considered finding a new therapist to do DBT and work with regressed/childish parts who will offer you more support? I and some others on PC do have therapists with more availability who will respond quickly between sessions and engage more deeply. I also do two sessions a week which helps a lot. My therapist refers to therapy as a re-parenting experience in some cases, and was in that type of therapy herself. She understands about meeting clients "where they are" meaning sometimes we benefit greatly from more attentiveness on the path to healing.

P.S. Just read your post about being "too much" a huge fear of mine. I find writing to my therapist between sessions so helpful and she's always encouraged it and assured me I will never be too much. I didn't believe her for a long time, but it's been 10 months of frequent contact now and I'm really starting to trust that she will stick around for me and not be overwhelmed. It's a pretty life-changing experience!

I think my therapist sees too, I'm not stuck in neutral, just reaching out all the time and being helpless- rather, by relying on her more, I make much faster progress, am doing the work and seeing the results, so I think we both find it gratifying.

I do hope you find just what you need.
