Read the New Testament, Proverbs and Psalms in the Old Testament. Don't try to go through the whole Bible right now - I don't think that would be helpful.
Have you tried Prilosec OTC for your chest pain? That happens to me ever so often. Take it in the morning with a full glass of water. It can take a week or so to really make a difference. It's good that you're going to the cardiologist, but if they find nothing, this is a good choice.
Rosemud is right about the exercise. So sorry about your problems.
