I love my sister. But her diet advice has included "just starve yourself!" and "chew it and then spit it out!" and it's not good.
Good lord.
Somehow I have to impress upon her that she has to stop talking at me about my weight.
I had to do this with my mom several years ago. Basically, I just told her that I was not going to discuss my weight with her anymore. I don't remember how I phrased it, but it must have been fairly forceful, because she got the message. But I was prepared to simply walk out on conversations with her if she brought up the topic again. Fortunately I didn't have to, but I wonder if that might be what it will take with your sister. Can you say something like, "I love you, but we just can't talk about my weight anymore. Pick any other topic, but if you start talking about my weight, I will walk out. I mean it." Easier advice to give than to take, I know.
Yay Lilty for a new job!
Aims, "beautiful woman" may not mean to her what it means to you. Kids get weird ideas about what words mean sometimes. It may mean "celebrity" in her head or something. Or maybe "my mom" is simply in a different category from all other female humans. Anyway, don't take it to heart.
This was my take on it too, especially since she says she's going to "use her imagination" -- maybe she wants to imagine you with blonde hair or in a princess gown or any of a thousand other things. You are truly gorgeous, and you're doing a wonderful job with her.
