your imagining what happened to your father and if you had seen the death of your father it would have been more traumatic for you,
I have seen the pictures of my dads Body on his living room floor blood everywhere Because these pictures was publicy put all over the net so yes i have seen my dad lying dead
And i do understand if i had watched dad have a heart attack i would feel just as bad watching so that must have been so bad for you sorry about your dad
