Yep that's me.
I took Xanax for 7 years and just woke up one day and knew that I felt different and knew that I didn't need it any more.
I didn't do anything, they just left.
It came on out of the blue and that's the way it went away, no reason it just came and went all on it's own.
In fact it's done that twice...when I look back on it now I know I was having panic attacks when I was a little girl, but at the time I didn't know anything was wrong, I thought everyone felt the way I did.
Anyway, the first full blown attack I had I was 16 and I had them until I was almost 23.
Then they just left, I weaned of the Xanax and never had a hint of a problem until I was somewhere around 29 or 30.
They came on the same way they did the first time, out of the blue.
Then one day around 6 years later, I woke up and they were gone again.
I weaned off the Xanax again and I've been panic and anxiety free for about a year now.
I don't know if age has anything to do with it or not, it may for some people but didn't seem to make a difference in my case.
My Doctor did tell me that when they come on for no reason and leave for no reason that most, not all, but most of the time if you look back in your family you'll find that someone else has or still does suffer from panic and anxiety problems.
He said it doesn't have to be a parent he said it could go back a couple of generations.
I came to find out that my Mom had them and so did my Grandfather...also several cousins have them or have in the past and this is all on my Mom's side of the family, yet I'm the only one of my Siblings who ever had a problem.
Sorry, that was a pretty long answer for a short question
