Suggest Remedy For Anorexia

My mom and my sister always get into fights and how do I stop it, also my mom puts her boyfriend before her own kids and all my sister and I hate her boyfriend and when my mom gets into fights with him she takes out all her anger on us, my sister that I ment earlier is kind of bratty she s like that because 2 years ago my parents went threw a difficult divorce and it affected my sister by becoming anorexic and all my mom did was make her life miserable because of her boyfriend instead of helping her out to beat the anorexia, my sister is also bratty because of my parents. My sisters and I love my mom because she does everything for us, she wants the best for us but her boyfriend brainwashes her to be a monster to us what can I do to stop this fighting and be a happy family with no problems
