To me that means that one's life is not restricted by, or focused around, avoiding, hiding, or fearing high anxiety states. It's not that one will never be anxious again, but rather, recovery means that one's anxiety will be in proportion to the event.
Total recovery is possible for many people.
However, for some people, particularly those who have had trauma in their lives, the tendency to react to life's stresses or painful feelings may trigger anxiety or panic attacks. While it may vary widely from person to person, treatment usually takes 12-20 sessions. By the end of treatment, one should have made progress towards their goals, as well as have a clear understanding of what they need to do to continue their recovery process. On the positive side, medication is very helpful for some people whose anxiety is very chronically severe, and often necessary if depression is part of the clinical picture. Sometimes people must try different medications before they find what works best for them, with the least side effects.
