I get shortness of breath and chest pains, like an anxiety attack / heart attack, if i have any contact with the family, like a phone call or mail or them coming by. It showed up on a Holter monitor years ago. I did aerobics, lifted weights, there were stairs in my apartment, i had sex - not a blip on the monitor. Dinner at granny's - danger, Will Robinson! It was still happening in recent years. Thats the main reason i cut contact - it was becoming clear that it was me or them.
