"Intense" is a good way of summing it up. Twice weekly often seems to stir things up more deeply, and many weeks it feels like it makes therapy and the content/issues we're working on have a larger presence in my life overall. On the flip side, having two sessions feels like it's better able to contain that intensity in a (mostly) manageable way.

It's definitely a net positive and I'm really glad I can go twice a week, but my current experience is that it makes therapy into a significant project pretty consistently. As opposed to my experience going once weekly where some weeks therapy felt like a big deal and some weeks it was pretty relaxed, and didn't register heavily or take much energy, 2x makes it feel almost like a work or volunteer commitment I've taken on, where the investment is expected/required whether I feel like it or not. And not in the sense that my therapist is holding my feet to the fire or anything, more that it's something my psyche and internal processes are holding me to and demanding I pay attention to.
