I need some reassurance. I'm really struggling with my anxiety at the moment. I feel like it could be panic disorder as I regularly have panic attacks for no reason. I have nothing to worry about however I'm obsessed there is something wrong with me and I'm going to die. I've had a heavy feeling in my chest for two days now and I'm constantly dizzy. I'm on anti depressants and beta blockers but I'm worried they're slowing my heart rate too much. It's 53 resting. I feel like I'm going mad and no one understands.
