Struggling with Panic Attacks and Shortness of Breath

This is me when I can't get a breath in. No matter how hard I inhale. It seems like that's it. No more oxygen. Which makes me panic even more. I count my fingers and tell myself to breathe. Like, literal manual breathing. After a few minutes I realize I'm actually able to breathe. (Pointer finger to thumb, 1 , middle to thumb, 2, etc. And then reverse)

I fear fainting or vomiting when I panic. It makes it very hard to go out, but I try to think to myself, so what if it happens? It’s not the end of the world. Maybe I’ll be embarrassed for a little while. Maybe I’ll feel a little off afterwards. But I’ll live! And I’ll be fine! I can handle a bad day, and then I’ll wake up tomorrow for a fresh start. Hope this helps!
