I heard "that impending doom feeling" all along growing up, from my mother, the psych nurse, to my brother, the one with the most behavioral and mental problems of the four of us. I would get it, too, I just never spoke about it.
But I had it from the age of 9 or so on, after a scenario on my mom's soap opera had one of the characters buried alive in a coffin intentionally. I was terrified it would happen to me. At 9 years old. I only recently stopped feeling gripping fear at the prospect that I would one day die.
It's no wonder we became drinkers, is it?
