It makes a lot of sense to me that you'd explore this topic in therapy. If you want to wind down and only have one more session though, it doesn't sound like enough time. You'd probably want to have some time to do the winding down, and this would be a big topic to get into. (IDK how big, but more than just a few minutes in a "winding down" session!) Do you have a choice not wind down yet, if you think it's important to discuss this topic with this therapist? Or could you discuss it with another therapist?
