Ooh, Tree, my T has done that, too--gotten so excited and invested in doing a new intervention. Often it scares me and shuts me down, because I worry that it's about 'fixing me' and that I need to respond well so he will be happy with me.
I'm glad you can see it comes from a place of deep caring for you

A lot of times I need to sit with Ts ideas for a few days (or weeks) so that they feel okay and become my own. Then, usually his ideas work, lol. I put a lot of resistance in!
I understand the huge shame factor. I hope that having T care so much helps mediate it a bit. You will find your way through it.
