I had anxiety for the first time in my life recently in the form of pain in my upper left chest. From a new job I hate (but pays well) and added to that my dad is very sick. Worse still is I'm the age my grandfather and his son (my uncle) died. I've read how people who have major stress in their lives develop a reduced ability to cope with stress. That seems like a terrible spiral downward.
