Earlier quoted context omitted.
Every time I try breathwork (be it box or x-y-z) I feel that the intervals are too long - by the time I finish breathing out my brain goes into panic mode and the next breath is not enough to compensate. I find them the exact opposite of relaxing.
A breath coach told me that breathing on a timer stresses some people out instead of calming them down. E.g., people who have experienced trauma. Submitting their bodily functions to an outside force's control can be very stressful. Her approach adapted breathing patterns to listen to your body's internal signals for when to breath in and out.
I'm also kinda ok with guided breath work of the "breath in, hold, out" kind but if I'm counting I get stressed out.
