I’ve hated my sister for a long long time and there are times where she is bearable and we can act like siblings, have a drink, laugh together. There are also a lot of times where she goes off the rails whenever there is a disagreement or whenever she doesn’t get her way, she’ll threaten to call the cops if we don’t listen to her and thrown stuff at us out of anger. We’ve tried to talk to her to get help but she doesn’t think she needs help and she will turn it around on us saying we are crazy and we need help and now she has a kid which is a huge responsibility. I know she’s a grown adult and she can do whatever she wants but she also brings up about sleeping with multiple guys and having foursomes with them, it’s just getting disgusting and to the point where I don’t want to be around or speak to her anymore. I feel like I’m overreacting but it’s been like this for 8 years and it keeps getting worse and I always get told to suck it and be there and I don’t know how much more I can do
