So I (17f) and my friend S (17f) where getting ready to go to her prom. When we where all ready we where relaxing and all of a sudden she said "Hey I don't want you to get mad but you look like a hooker." And I didn't know what to say so I just laughed and said thank you ig.

I then told my mom and she was pissed. Like really mad and said that she was gonna tell her mom and that she should look in a mirror before she comments on someone's look. And that how she dressed was a absolute mess. My mom also said how S is very envious of me and how when we where taking pictures that S looked at me with a grossed out face.

I then told my sister and she called S a bitch for calling me that and said then I need to stop being her friend. And honestly yea I want to stop being friends with her at this point. But my mom and her mom are friend and I'll feel bad for my mom to lose a friend. Idk what to do. I mean I'm not mad mad but I'm mostly just surprised that she would call me a hooket to my face after she asked me to do her hair and make up.

What do I do?
