How to maintian peace in mind while having trouble breathing?

Intentionally, I slow down all movements but be aware physical symptoms. When I’m anxious, my head is usually spinning, my chest feels suffocated and my limbs are a bit numbed. I would sit down, close my eyes and I would do a yoga deep breathing exercise where you take a long deep breath and exhale longer than you breath in. The next breathing exercise I usually do is I do during running to prevent myself from getting out of breath. I would take a deep breath and let out in 2-3 intervals like “ ha, ha ,haaaaaaa” and repeat as needed. I find this helpful when I have symptoms of chest pain.

Whenever I have trouble breathing or realize I'm starting to get anxious (my breaths become shallow). there are several things I try doing: 1) I try to lessen the "stimulation" around me. For example, I tend to start getting into my anxious mode when my mom starts shouting. If I'm in the middle of listening to music, I lessen the volume or listen to something more soothing. For work, I tend to start getting anxious when I'm doing research and get frustrated about not being able to find what I need. I realize I have too many tabs open, then I start cutting down. 2) Breathing exercises. I have seen beautiful gifs that you synchronize your breathing with. My personal favorite is the opening and closing of a mandala flower. Aside from helping me focus on something peaceful and beautiful to look at, it also helps me with my breathing. It also helps me refocus thoughts and calm down. 3) There's this thing they call "grounding". It's when your thoughts are racing non-stop all over the place and you're having trouble breathing, and you try to "ground" yourself back to your space. I think it's a sort of mindfulness where you touch something in the room and just let yourself feel what is real, "this is a chair. I am sitting on the chair." Something like that! There are many other sources that can explain it better :)

It sounds like a struggle having to focus on peace while breathing is an issue. To help myself regulate my breathing I have always followed a count down technique, this helped me a lot. I would find five things I could see, four things I can hear, three things I could smell, two things I could touch and one thing I could taste. Following through the thoughts helped take my focus off trying to breathe and just allowed me to breathe naturally. I personally found that the less I think about breathing, the easier it is for me to breathe! I hope this helps in some way, and please adapt it to maybe your favourite sense more, so five things you can taste, or even touch!
