question: Hello,I'm a 20 year old male experiencing moderate chest pain and tightness, as well as at time having a hard time breathing due to the "heaviness" in my chest. They started a few months ago after a year of virtually no exercise (continuous bedrest) and eating either fast food or processed meats for every meal every day. I also consumed a medium-sized bottle of ketchup daily, for about a year. One day, during a very large meal my heart began to beat very oddly and was moderately painful. These pains continued and I went to a clinic shortly after. It was dismissed as anxiety. I have been acutely anxious as well, at most times very tense and stressed, usually about nothing, however I never had chest pains. It has been a couple months since then, and the chest pains have continued, and in fact worsened. There are points when my chest is extremely tight and I feel as though I cannot breathe. Also, my anxiety has diminished greatly during this span and I frequently meditate to relax, and stay relaxed throughout the day. Almost any time I am emotional, my chest begins to hurt. Recently, I have had pain in my upper-middle-upper back as well. Palpitations occur multiple times daily. I have begun to dismiss all of these symptoms as anxiety however the thing that I continue to debate is whether my past extreme anxiety, coupled with my consummation of fast food or processed meats (chicken strips) daily for a year as well as a completely sedentary lifestyle have perhaps  caused a problem with my heart. For the past month, I have improved my lifestyle habits drastically and continue to have these pains.Thank you for reading :)
