That my grandma (father's side) killed herself.

Grandma was straight out of r/raisedbynarscissists. The problem was in her brains department - mediocre all around - so in the end she, I guess, failed at building her narcissist empire. She managed the first step all right - grandpa was submissive to her, but a very smart engineer (with some patents to his name even). Then in all went to bits, though. My dad rebelled after she threw his ship in a bottle out the window in some insane power move. She tried terrorizing my mum (to no effect). Then tried to turn us against our parents - that was actually semi-successful, but things came to a head when she took the three of us on a long vacation with the goal of having long "your parents are horrible people" conversations with us. We told on her. Parents arrived 5 hours later. There was much shouting. And so it went on for the next 30 years...

Then grandpa started developing Alzheimers and everybody else grew up, so we didn't have time for her nonsense no more. There was much whining about how sad and alone she is, there were some threats of suicide, some shenanigans with sleeping pills, some visits to a psychiatrist. Then one day I got a phone call, and that was it. Turned out she actually had a stash of these pills, literally hundreds of them, and I guess she decided to make the final statement.

Well, dad cried quite a bit anyway, he is like that. Soft heart, doesn't like to see people unhappy.

Funny bit, depending on how you look at it: since she killed herself with style, vampire in a coffin position, propped up on some pillows, after her jaw got slack it assumed a very zombie-ish quality, hanging down pretty wide. As the cognizant-adult-in-attendance I had to take grandma's clammy, very dead head in my hands and tie up her face with a piece of cloth. Not an activity I would recommend on recreational grounds.
