So I had my first panic attack today. And it scared me to death. I felt like someone was sitting on my chest and I couldn't breathe. I was sweating like crazy and couldn't hold a conversation I was shaking so bad. I felt like I couldn't control anything. Ironically I was on my way to the Psych Clinic.

I'm trying to find humor in my struggles.
My question mostly is I am home now and I can't seem to get rid of the tightness in my chest. I took a Klonopin I have for my bad days but it hasn't help with the chest tightness.
Ideas? Or is this normal for a while after a panic attack?
