Wow a heart attack? Make suer you take care of yourself and put your health first.  You have officially been given the "I don't sweat the small stuff Pass" and a "No drama Pass"  Make sure you use them whenever you feel the things getting stressful.   No need for your body to work on healing and dealing with other "non-important stress" like what comes out of some people's mouth.

I guess you are about to become a really laid back person.
