My sister takes legal substances to help with her depression and divorce and processing childhood abuse, but she's really mean and insecure and victimizing everytime to me and my partner. I can't tell her because she will get overly defensive and rude and try to turn it back around into me. I'm not always the nicest person either but I'm honest about it and not hiding it behind bullying humor. She threw a big plant at us, makes fun of our interests, says we aren't responsible, tried to project her marital issues onto our relationship, body shames women on tv or belittles their intelligence to bodily comments, keeps claiming bs past stuff and then claiming it's too soon to joke about it to us. She created a game with her friends to act out loved ones flaws as charades so she can guess them by their behavior that she doesn't like for fun. I have pots (illness where you faint) and she once acted out how weak i get and pretended to faint dramatically which i don't do and that really hurt.
