what do I do if I absolutely hate my step sister
she's 18 I'm 13I try to be nice but she's always being a jerk to me
When you absolutely can't ignore her (which will get on her nerves), be so sweet to her she'll wonder what you're up to. (That'll really freak her out, which would be super fun):-0
Find a reason to like her.
Talk to her about what you're feeling.
Try to talk to her about how you feel.... That might help!(:
