When i was fresh out of high school and had only recently gotten my first job, i left home for a few weeks and stayed with a friend because my family situation was a big toxic shit show, largely thanks to my mother.
The night that I announced this to my parents they both seemed kinda indifferent, but the next day when i was ready to leave, my mother basically threw an enormous tantrum. Though she said and did a lot of objectionable, outrageously shitty things that morning, i think the worst was her telling me that she'd looked up ways she could kill herself with her meds the night beforehand, after I'd told them i was leaving. Then she followed that up with threatning to kill herself as soon as i left.
That was bad on its own, but a day or two later, after things had at least calmed down enough for her to quit screaming at me, she admitted (almost gloated, actually) that she made the suicide shit up because she wanted to "make [me] feel as bad as I made [her] feel."
