A lot. Like, a LOT. Too much. Urgh!
It beats thinking about the trauma itself, tends to be more productive. But I spend a lot of time actually in therapy throughout the week, so I'm finding it really important to close the door on the therapy thoughts and deliberately engage my head in other stuff during the day. I'm just going to crash and burn otherwise.
I do it like a thought diffusion exercise, which is kinda like a mindfulness thing. Thoughts about therapy show up (again), I notice them, remind myself that I'm working on something else right now, and I'll come back to the therapy thoughts when it's the right time. Don't fight them, just put them to the side.
Balance, for me, is so hard to get right. Finding the happy middle between riding the back seat in therapy (and getting nowhere fast), and waaaay overdoing it (leading to the crash and burn), is a constant work in progress. The amount of time I can "work on" my junk continually changes with my mood and life.
And while I'm continually butting up against that whole "let's get this over with" thing, it's actually rebuilding the rest of my life that's the important part, not the therapy or the trauma. Therapy is really just a tool to help facilitate that rebuilding process, so meaningful activities are really the key ingredient in my recovery rather than therapy per se.
