Friend who's never had a panic attack: What's it like to have a panic attack?

Me thinking to myself: boy have I got a story for yoooou!

Me out loud: uh, it's different for everyone. For me it's like I'm trapped in this tiny box. And no matter what you can't get out. The air in the box is slowly driving you more and more insane. Soon your mind blanks and all you can do is scream, laugh, and cry. Soon the box goes away but by than, you're mind has already left.

Of course, when I was explaining it to him, it was way longer and more complicated. This version was the cleaner summary
