When someone knows they're about to die, it's not uncommon for them to drop a bomb of truth on loved ones. Sometimes it's a petty or funny confession, while other times it's a dark secret that was kept sealed up for years.
While receiving an emotional bomb on top of grief itself can feel overwhelming for those left behind, it makes sense for the dying to feel at peace with unleashing their mess.
They don't have to worry about answering tough questions or getting emotionally reamed when they're dead, so why not let one final cat out of the bag, consequences for the living be damned?!
I'm a medical student and I had a female patient who was new to our practice who was HIV positive. I needed to ask her how she got the virus i.e Sexual or IV drugs. She tells me it was sexually transmitted, and the only reason she got tested was because her partner of 3 years last words to her as he was dying in hospice was "I'm sorry, I'm sorry, I wanted to tell you; forgive me." Heavy stuff.
