Lefty, that's a powerful story. Thank you for sharing. It's "nice" to a degree that we can come here and discuss these things. It is part of the healing and growth process, for sure.
My mom sounds a bit like yours. She probably has an undiagnosed mental illness, perhaps PTSD of some sort from her childhood which she refuses to share and one she refuses to acknowledge. She has passed on much of her madness to me and she has become a trigger for me. She has limited sympathy for anyone inside her family.
