Doctors sometimes prescribe beta blockers for anxiety, but there are also many more out there to specifically address anxiety in my opinion. I would go back and talk with my doctor about all of your options, however, he/she may have a reason for putting you on this for your anxiety. Another important step is to seek counseling to get to the root cause of your anxiety. In my experience, the knowledge gained can really help you confront and deal with it.
