Basic answer is yes.
Do pay attention to your breathing. It is not easy but if you can take slow, deep, even breaths, focus only on the in out of breathing, it will eventually help.
Breathing heavy adds to anxiety by decreasing the oxygen supply to organs, including the brain and gut...it is the way we breath when frightened, (of course)
There are things that work for me that I can only do a certain times (like, literally jump into a lake/river/ocean and swim/float...)
Also, usually others cannot tell----I went through nursing school, many jobs, being told, at times, how calm I am while at the same time having panics that caused me to not feel my body from the waist down, to feel that I was dying, that lasted hours, etc.
At work...intense jobs actually helped...the ones with little ******** and a lot to manage; otherwise, when just really stressful anyway, I will go to the bathroom, or wash my hands while practicing breathing...& I will always volunteer to run for something, up or down stairs, corridors etc-----
I have a few visual flashes, but more often it is emotional/sensory in other ways---something triggers me into "that" place, it is not easy at all to see the connections...
