It doesn’t make your sister look good to people to be trash talking you. The ones who know you, know you for how you represent yourself, regardless of what she says. The ones who don’t know you really don’t care. It goes in one ear and out the other.

I know it feels awful to be maliciously gossiped about. Hold your head up high. You know the truth and that you are a good person. Get away from your sister as soon as you can to save your own sanity.
