Texted my P asking for a tranquilizer or something but I’m sure she won’t give it.
You may have answered this but why do you think she won't give it? Even a low dose of something like Xanax helps tremdously for me. I had to lower my dose per my pain doctor due to being back on oral pain meds but even half of a .5 mg of Xanax helps and of course I can take the entire .5 mg and it really helps to settle my mind to allow me to focus on my breathing.
For the hyperventilating due to anxiety and mainly panic, I do a few things. I first try to settle my mind. Though it feels like I'm dying, I'm not. And that helps me tremendously. To make myself understand that I'm not dying. It helps me to settle my mind so that the focus on breathing helps better.
I then just focus on slowing my breathing. Not any special breathing exercise. Just slowing down my breathing. I naturally breath shallow and that doesn't help this. It's because I was being drowned during my trauma and that caused me to naturally breath shallow so I try to force myself to breath deeper. But I will count seconds. If I am breathing in and out super fast I will try to make myself breath deeper for a second, out for a second. In deeper for a second, out for a second. Then I will slow it even more. In for a 2 seconds, out for 2 seconds. In for 2 seconds, out for 2 seconds. This may have a name but I don't know the name and honestly, for me, it doesn't matter.
I was hyperventilating in an ambulance once and one of the people in the back was threatening some sort of breathing medical device if I didn't stop hyperventilating and that was making it worse. So, one of the other guys in the back was like "breath with me" and that helped a lot. Breathing with him. He would have me breath in with him, out with him. And that helped like instantly. So I found a video on YouTube that was about slowing down your breathing and so I can pull that up in a second, during panic, and am able to do the exact same. In with the person on the video, out with the person on the video. I made that video be on the homescreen of my phone so I can pull it up fast. And so that's another idea. Try to find a video that you can quickly get to in a panic and try to breath with the person on the video.
The name of the game when it comes to hyperventilating is trying to slow your breathing down. I'm sure others have good suggestions but this has worked for me. I don't worry about special breathing exercises. I first remind myself that I'm not dying. I'm OK. I'm safe. Then I just simply force myself to breath deeper (which I can do if I am thinking about it) and slowing down my breathing just by counting the seconds. In for 1 one thousand, out for 1 one thousand (how I count seconds). In for 1 one thousand out for 1 one thousand. Then in for 1 one thousand, 2 one thousand, out for 1 one thousand, 2 one thousand. And though I have needed to get to 3 seconds, usually I'm no longer hyperventilating after the 2nd second.
Hope this helps! Hyperventilating really sucks!
