I am so sorry. My one sister acted like she hated me a lot of the time. I never knew what I did to her. She said my son was a serial killer. That almost did it for me. I finally forgave her after a few months. He was acting out. Turns out he’s bi polar. No relations to serial killers at all.She died last year and I miss her. I wouldn’t even mind if she called me up to yell at me now.
I hope your daughters figure this out before it’s too late and what a terrible position for you to be in.
