Does anyone else get panic attacks?

Last night I had a panic attack inwhich I screamed my head off for what felt to me forever, but to everyone else about 2-3 minutes.
I felt absolute fear, I started running through the house. But stopped short and came to my senses.
What kills me is that I had a great day yesterday, and I wasn't thinking of anything troubling or bad when it happened.
Now I'm walking in this gloomy mood and in a state of fear.

How does one shake these things off?
I'm having a good day except for what I'm feeling inside.
Work has been pleasant and my kids are being good.
I'll try watching a movie or playing a computer game, what I really need is a hug fest.
Thanks for listening.
