I'm going to ask my aunt to stop sending me unsolicited weight loss articles/tips
Why is she even doing that to you?
She thinks I am fat but I am a healthy weight.
I agree. She should stop sending you stuff like that, especially since you did not ask for it. I think that that is just rude.
I'm going to tell them I'm upset with their pushing weight loss stuff onto me. I'm going to tell her off if they keep doing that.
Great. I hope you say it gently but firm. You may need to block her temporarily on social media for her to stop.
