TITLE: My mom [45 F] keeps telling me I [16 F] look like shit. It is making me not like her. Is there a way that I can improve our relationship?
POST: My mom does a few things that really get to me. One of them is that she keeps telling me how bad I look. To be honest I'm very unpopular, socially awkward, and don't look very good, but I am trying my best. And her comments aren't constructive, because she doesn't mention what I could be doing differently, unless it's forcing me to go to a stylist, get my arms waxed, or to a tanning bed. When we're in public she will whisper into my ear that I look terrible, she will make fun of my posture and body type, and it just makes me feel bad. I started being vocal about how it hurt my feelings a few months ago. She says that there's nothing wrong with telling me I look like shit, that that's just how she is, and started telling aunts daughters that they look like shit, and when they smile awkwardly at it, she looks at me and says "see? It's normal". I say that even if they think it's normal, that it hurts my feelings, but to her it doesn't matter that it hurts my feelings because she thinks she's right. She doesn't even budge if I'm crying, and I think that's really mean of her. She tells her friends what a difficult child I am and it makes me feel bad, I wish we had a better relationship. We get along a lot of the time but she does this so often that it's making me not want to be around her, and it's affecting my relationship with my other family members because they think I'm a bitchy crazy teenager.
TL;DR: 
I want my mom to be more considerate, she says that this is just how she is. I'm starting to really not like her. What are my options?
