Beautiful Girls Are Lonely Too?

I have this good friend of mine who is absolutely beautiful, she has one of those faces that once you see you remember because since she's mixed with so many different races that her look is so different and exotic (personally I think she should be a model but she wants to teach) and along with her beauty she's very smart and is involved sports. Me being an ugly chick look at her just envy spills from every part of my being but just a couple days she got kicked out of her house and has been living with me. Her parents are both alcoholics and she lives in a two bedroom apt with 3 siblings, and every night she's been with me she's cried herself to sleep....I couldn't believe it. This girl who I thought had everything was crying her eyes out and telling me how much she hated her life...I still don't get it, because I'm ugly and I would kill to have people look at me the way they look at her...reminds me of that song Lucky by Britney Spears....IDK why im on here telling you guys this but I just don't understand how someone could have almost everything and still fell so sad and lonely?
