Panic

Have you, on more than one occasion, had spells or attacks when you suddenly felt anxious, frightened, uncomfortable or uneasy, even in situations when most people would not feel that way? Did the spells peak within 10 minutes? (Please check the box if yes for either.)
At any time in the past, did any of these spells come on unexpectedly or occur in an unpredictable or unprovoked manner?
Have you ever had such an attack followed by a month or more of having another attack
