Why does she treat me like this?

My cousin and I'm the same age, 22, she has a boyfriend and comes from a long line of money. Her mom is a nurse so she thinks she is everything and more. We use to be very close because we're only months apart, I do believe that is the problem now. All through school we had each other we didn't have friends because we always hung out together! Now that we're older she is driving and hanging out with her boyfriend. I don't have a boyfriend and hers always wants me and my sister to go places with them, she doesn't like that idea. She always has to run out and get the top notch stuff like stuff that tops what I have. She went out and got a new Iphone, always is buying new jeans like from the mall. I have to work for everything I have and can't afford to go on vacation every couple months. I'm in school to be a doctor and she keeps telling me I need a new career. She is in school for grief counseling and everyone always tells her how proud they are of her. I can't stop being jealous, I mean she has it made, the perfect life, a boyfriend, money. Today she fell on the ice and the school nurse told her to go to the ER and I told her I would go with her but she told me to stop worrying about her and she didn't need me to go to the ER with her. Why does she treat me like this? My family even treats me like this because they think she is everything. She told me that the doctor that seen her today hit on her and he told her how pretty she was. Guys don't' look at me, I try so hard but no matter how good I do in school or how much I succeed my family will always pick her over me, I need suggestions on how not to let her bother me and put me down anymore.

Aww i wanna be your friend, if you have a kik then you can kik me, mine is muffingoesmeow. You should just pretend like it doesn't bother you for the most part. Don't really pay that much attention to her

I hate to say it, but it looks like your cousin thinks she is more superior and better than you, just for reasons like money, etc. If I were you, you should maybe confront her about it, but when you two are /alone/. If you can't do that, then perhaps you should try to avoid her. I know it sounds horrible, since she's your cousin, but constantly comparing yourself to her is unhealthy. In my opinion, you're doing fine and even if you don't have as much money, think about what matters.
