I have fond memories of my mother during my childhood, baking, beach days etc. until I turned 12/13. It coincided with my older sister 18/19 having a baby but in my mind that can’t be the reason. She turned absolutely vile overnight. Didn’t speak to me or look at me. Screamed at almost anything. Stopped buying any nice food or clothes for me. Tried to humiliate me in front of anyone, reading diary- spilling my secrets.. I was behaving. School was my lifeline so I was glad to be there. Passed GCSEs and A levels. Went to uni. I’m older now and I find it very difficult to forgive her behaviour. She was also vile to sister but treated baby very well. Dad was there, financially comfortable. I don’t understand why but wondered if anyone else had experienced this.
