I constantly worry abouy dying. When someone my age dies or just anyone in general, it gets worse. I don't necessarily fear death itself, but I fear leaving behind my daughter and husband. My friends wife who is a year younger than me just passed away from a clot in her heart, then within the week a few celebrities died of heart attacks. I have read up on symptoms of heart attacks and clots and suddenly I started feeling the same symptoms, but extremely mild. Is it possible to trick your body into feeling things that aren't happening?
