Has anyone gone from being a relatively non-anxious person whose an extrovert, to being completely anxiety ridden and introverted after a single panic attack?

A few months ago I was at a going away party and like the snap of a finger something changed in my mind. I found it hard to talk to communicate my hands became numb and I was terrified. I decided to take a nap and try to sleep it off. An hour later I woke up to the worst panic attack of my life my palms were wet, my heart was beating out of my chest and my mind was going 1000mph with crazy thoughts. And ever since then the feeling has never left me 24/7 the sick anxious feeling clouds over me. Some days it’s better but sometimes it gets bad and I find myself having 2-3 panic attacks a day and I don’t know why. I don’t know what to do. Has this happened to anyone else?
