I'm sorry that this is causing you panic!

I don't think I can fully relate, but I can share a breathing and panic story.

I was having well, a lot of stress and depression going on. I'd had a few panic attacks. It got to the point where... somehow my body just WASN'T breathing. During normal activities where I wasn't actively paniced or stressed. I'd just start choking because I hadn't breathed in for a while. Or where I'd gasp in a breath because apparently I had been holding my breath. I wasn't doing it on purpose and wasn't aware of it until I gasped or choked. It had me fairly worried actually. I had to really focus on my breathing for a week or so until it seemed to sort itself out.
