I really enjoyed this, it actually has a bunch of really helpful ideas to help cope with panic attacks and even deminish their affects which is awesome...
I suffered from anxiety and really bad panic attacks myself for a short while until I learned how to rid myself of them.
It just so happens I wrote a post myself about this and though I don't usually self promote on this platform I think it might be of service to anyone who may read this and could possibly find relief in both what you've shared and what I've shared coming from someone who's gone through it and beat it.
