I have terrible anxiety and panic attacks and am being treated with Citalopram and Klonopin daily. This weekend I had a moment of heart palpitations that lasted a few minutes. I could feel my heart skipping. It freaked me out and instead of deep breathing I took a Xanax to calm me down. Now that's ALL I can think about. The palpitations are what started my whole anxiety mess in the first place.

Does this mean my medication is not working? How do you deal with setbacks like this?
