I actually asked the same question a while ago and got some really good answers. Here's the link....

I think I was looking, like you, for a success story, for reassurance that one day this would all be over and I'd be back to normal. I wanted to hear that I was going to be cured 100%.
That's not the answer I got, and it scared me. I was in such a scary, dark place that I couldn't imagine living the rest of my life like that. The reassurance from people that it gets better did little to comfort me, but they were right. It's true, it does get better.
I don't think my anxiety will ever completely go away, but it's a million times better then it was. My panic attacks and bad anxiety moments are fewer and farther between, and they're not as strong anymore. And most of the time I feel perfectly normal, which is a feeling that I thought was gone forever. The numbness, internal shaking, twitches, insomnia....it all gets better, and it does go away eventually. Those things still happen to me once in a while if I get too stressed out or let me anxiety take over, but it's not all the time like it use to be.
So I don't know that anyone has completely recovered from anxiety, I get the feeling that it's something that's always going to be there, and it can pop up at anytime if you're not careful. But if you are careful and you take care of yourself, then yes I think you can achieve some sort of recovery.
