I am not sure if this is the right place but am in distress. My sister1 moved out around September/October of last year and was living with her BF. Many things had happen to her during her time there but I will spare you the details. She came back but she has mental breakdowns and is unable think right. I for the most part can help her calm down but my other sister2 doesn't want to accept her and she thinks of her as a home wrecker. I understand where my sister2 is coming from but I am not sure how my sister1 is gonna take it. I currently do not live with her and lives with my dad and brother. I am not sure if they know how to handle the issue. I can do the best I can but what's the appropriate method to deal with this?
