I think that it's insanely rude at this point. As a 16 year old I suddenly went into this phase where family members would gush over how pretty I was- as well as my mother's friends. Ever since she's been very harsh over my appearance. For example she'll tell me not to eat certain things so I won't get too fat, tell me not to get fat or it'll ruin my figure, how disgusting my hair looks, and basically wear nice clothes alll the time that'll show off my figure. She doesn't do this shit to my other two sisters. It's always me. Always reminding me to stay pretty as if that's all I'm wroth. Should I say something? Isn't this considered abuse?
