I think you are right. She also said " I have longer hair than you, more friends and I look better." We are not children. We are in our twenties. She always had complaints about me growing up and everyone. That she's so invested in looking better than me is sad but it's always been an issue for her. She is significantly larger than me, had bad acne and struggled with hair problems growing up. I was pretty popular and always had longer hair, never contended with acne and was fit. The same is still true. I never once compared us but she always has. I may have looked great on the outside but anxiety has tortured me for practically my whole life. What she thought/thinks has been a bed of roses has been a hellish existence filled with mental anguish - made worse by physical abuse from my mother early in life and now my younger sister.
