Hi, so I’m a 21F and I’ve had severe panic disorder for just over two years now. It’s a complete chore, as you guys will know and I hate how it’s affecting my family as they’re so worried about me. My panic attacks are two/three times a day now. I ended up in hospital the other night being given sedatives because I had the most violent panic attack I’ve ever had. I started new meds today and also booked an appointment with a hypnotherapist that my doctor recommended to me. 
Today was also really bad. I could feel a panic attack coming on and with me, it’s become a “fear of the fear”. What I really want to bring up is the chronic pain that comes along with anxiety. The chest pains specifically. I called an ambulance completely convinced I was having a heart attack (as I have done many times in the past). Even while calm I have a nagging in my head telling me that I don’t have anxiety, I have heart disease. No matter how many doctors tell me that I’m healthy aside from my anxiety, I just cannot believe them. 
I live my life in absolute fear, I’m petrified. Please can anyone lend advice on how to assure myself that there is nothing wrong with my heart?
