This fat friend is always competing with me in school and it's so annoying. She tells you something in a way that makes you think that your opinion is not okay. She acts like a know it all. And she is lowering my self-esteem all the time. I don't know what to do, I can't tell her anything about her weight because I don't what to be so rude. But I just deal with anything she says to me.
Thank you for you answer. I will try to do that but you know the problem is that in school all girls are connected in some kind of a chain so if I go out with one girl then all girls go out so it's kind of inevitable but I will try my best anyway ;)
