Sorry, I was wrong. It was
panic disorder I had. Brought about by my PTSD. The type of panic I had was because I was left with an overly sensitive "fight or flight" response owing to past events. Those kind of panic attacks drop out of nowhere without warning going into full blown panic instantly. There's a massive difference between those and attacks brought on by hyperventilating. So my advice is probably useless to you freedomfries, just ignore it. And hope you find relief soon
