Yea panic attacks are the scariest things and they aren't necessarily the same as each other. You probably already know this but could you try carrying a paper bag around with you to breath into just incase this happens again - it will help. Some people confuse panic attacks with a heart problem when they first experience oneand are rushed to the hospital, only to be told they 'just' had a panic attack. Shows how intense these things can be. Most important thing to remember is though that a panic attack can't kill you, and it will pass.
I had my first panic attack at eleven years old in a crowded school assembly hall and wondered what the hell had just happened to me. I never told a soul about them either (I always managed to hide them well). For many years I really thought that I was either going mad or had something seriously wrong with me.
