I have several stories
My mother cooks a lot for her church so when I was twelve during her pastor's appreciation dinner, a elderly man told me how I should stop eating all together, I cried in my mother's car and refused to go back in to the church.
When I was 14 I was over my Dad's house for Christmas, when my Grandpa told my family loudly how I need to step back from the dinner table once in a while.
In Catholic school I was bullied for being fat, but the ringleader was bigger then me and would usually "you're as big as a desk and next year you will be as big as two". She would always try and get me into trouble at school, eventually I got expelled form the school and blamed for something I didn't do.
I broke a desk in middle school and everyone laughed including the teacher.
Looking back on my Catholic School experience I relished that she was also hurting and she took that pain out on someone weaker.
