why be mad at your sister for something she can't control? you said it yourself, she didn't work for it so obviously she would have had all those things no matter what. she didn't chose to have whatever personality trait that makes people like her. and she most likely didn't ask your mother to leave you behind. so why spend all this time and energy on something that can't be resolved. youre never going to go back in time and have your mom take you with her or have your sister not have friends or money... its too much effort and energy into something with no results. it sounds like, if anyone, you should be mad at your mom, not your sister. she didn't ask to be born and thats basically what youre mad about. sorry your mom did all that to you but you can't take that out on someone who had no say in your life.
