I have recently had several af episodes. I have been extremely frightened by these as I have never experienced them before. I have had panic attacks earlier in 2016 and wondered if these were, in fact, af episodes on a milder scale? I am on Rivaroxoban and now being told that there is no antidote if I experience a serious bleed. I feel my life has taken a major turn for the worse. Can I overcome the feelings of anxiety that this situation is causing me?
