I hate my stepfamily especially my 11-year-old stepsister
Why do you hate your stepsister? She's only 11.
I can't stand her. She's disrespectful to me
Well every 11 year old is honestly. You should try to embrace the family that is making your parent happy again.
What kind of bull shit answer is that? You are not helping me.
Because trying to accept and understand people, especially kids, will make your family happy. Your stepsister is probably going through a phase and needs guidance to get through it.
