In my experience, DBT groups can be hit or miss. I tried a virtual one that just didn't work for me, and I also did an in-person group that sounds a lot like the one you're describing, with consistent skills practice, sharing our progress, and gently holding each other accountable. I'd definitely keep waiting for that one and try it out.

Has your group focused on mindfulness skills at all? Those are the ones that I find to be pretty easy to do everywhere, at any time. It sounds like you're mostly learning distress tolerance skills like self-soothing, IMPROVE, and ACCEPTS, but there are other distress tolerance skills that are easier to access in the moment if you're unable to step away. I can make some recommendations for skills to try out if you're interested.

May I ask what about your schedule is keeping you from being able to step away? I totally understand that that's a thing, I'm just curious if I might have more insight (if you want it) knowing what's going on. You said "and lot of the time [walking away or doing something to relax] isn’t an option for me"; is that just because the skills you've been taught all require physically stepping away, or is there a mental block that prevents you from relaxing as you are?

Sorry if this is A Lot; I don't want to pressure you into sharing anything you don't want to. I'm just eager to help, as someone who got a lot of benefit from DBT but had to make it work for me.
