I really am loosing my mind, i am still not married but living with HD and his Daughter. she is worse then ever, lying, stealing, ruining things. Today i grabbed her by her hair, i have never done that to anyone before. she is turning me into a different person. she told me yesterday that she wakes up every morning and thinks about how she can make cry, that when i am sad/mad it makes her feel good inside. she likes it when we yell at her because she knows we are unhappy.

i litterally have done everything in the book, being passive, being aggressive, removing things, rewards. im at my wits end. im loosing my mind.
