I hope this isn't out of scope for this thread but I've been wondering for a while. The left side of my diaphragm is paralyzed due to a sloppy surgeon many years ago and I wasn't sure how that affects the whole breathe from the diaphragm thing? I sometimes try breathing practice but it just increases my anxiety.
I suspect your most powerful source of information on your particular case is going to be your own experimentation.
You have to breathe anyway, so it's not like we can advise you to stop breathing until you ask your doctor .
My suggestion would be to try breathing practice but don't go at it very hard... just take a very easy, mild approach, and see if you get any positive results.
