Welcome. I just thought I would stop by and offer my two cents. I, too, have experienced anxiety but it wasn't 24/7. Mine was just every single night. It still is for the most part just not as bad or as long as it was lasting. I had the exact same symptoms as you and the thoughts of having a heart attack and dying. Let me say this. You are not going to die from anxiety. I was just in the ER a couple of nights ago and insisted that they run some heart tests on me to make sure that my heart was fine. Everything came back okay. They said that my heart was wonderful. I told them that I didn't think that my heart was wonderful from the way it felt. It felt like it was going to leap out of my chest. So anyways, I just wanted to add also that you are not alone. A lot of us here are in the same boat and we are here for you if you need somewhere to go. Keep us informed of your progress.
