In my 18 years of working with people who suffer from anxiety, I've yet to see one person cured by medication. Don't get me wrong, I think medications are a wonderful tool, as they can be highly effective for reducing anxiety, worrry, and panic.
While there are biological factors contributing to the experience of anxiety, there are also cognitive, emotional, behavioral, and stress factors that need to be addressed. Stress management, abdominal breathing, progressive muscle relaxation, and cognitive behavioral therapy (CBT) are all a part of a comprehensive treatment approach.
So, to answer your question, you may see a return of symptoms if your doctor takes you off of Lexapro after three months. Discuss this possibility with your doctor, and what the treatment plan is if your symptoms return.
On the other hand, you do not necessarily have to take it forever if you work on learning these other techniques. Look for a therapist who specializes in anxiety disorders. You can find one in your area by searching at the Anxiety Disorders Assocation of America (ADAA) website.
