Have you looked into getting Propranalol? It will regulate the release of adrenalin and also regulates heart beat so your heart doesn't race but just beats normally. It can help break the chain of anxiety.

I went to see a cardiologist recently and he said a racing heart is extremely common and nothing to worry about. Of course, it's always good to get it checked out. He suggested when I get palpitations or my heart races to remind myself it means that my heart is working just as it should.

I have this too, 24/7, for the past three years. I've done a lot of googling on the subject. I learned that the chest pain is actually from the muscles tightening due to the anxiety and shallow breathing. Go onto youtube and search for meditation videos, anxiety videos, and breathing exercises for anxiety. Some of them are very helpful. Exercise helps too. I record an exercise show and try to do it as often as I can. I always feel a little better afterwards. It's my choice not to go on meds. My dr prescribed Lexapro and after I read the side effects, I didn't want to take it. What you describe is all part of the vicious cycle of anxiety.

That is exactly what a severe anxiety attack can feel like, a heart attack. A lot of people go to the emergency room because they think they are having a heart attack when in fact, it's anxiety. But when in doubt, see a doctor. Hugs GB

There are days when I can't leave the house and can't function in my business because of panic attacks. I stay in bed all day waiting for them to resolve. I take Xanax and use food to abate the symptoms. I've gained weight and the weight gain is another source of anxiety as people often call me out on it. :(
