I'm going through this therapy now where we talk a lot about the breath and visualization. I've done DBT, so I know about the mindfulness part of it, but mindfulness is enigmatic and can be easy to drop. If I'm not driving (!!), I'll either stare at a point or shut my eyes and concentrate on breathing. I think of something pleasant or pleasing. I touch my top or my pants. I try to breathe through it and concentrate. I used to have a lot of anxiety in the NYC Metro system. I didn't like the elevators or feeling trapped. I had to breathe and try to touch the wall or something.
I don't know if this helps.
