So my now 12 year old sd moved in with my husband, my now almost 3 year old daughter and I about 2 years ago. She was taken from her mother by cps because of drugs and some other issues. I feel for her that she has gone through a lot in her life but she has basically shown herself to have absolutely no respect, manners, or compassion towards any other human being. She constantly disrespects her father by calling him idiot, stupid, fat, loser, etc. Never says please or thank you, has on several occasions laughed at her little sister when she was crying in pain, and has told me she does not care about people only animals. Also recently she screamed at my husband, my daughter and I "I hate you all and I hope you all die in a fucking car accident" as she flipped us off. This was in response to getting grounded from her tablet for the weekend for calling her father an idiot. I am at my wits end and my husband is getting there. MY husband works weekends (off on thu.& fri) and works 2pm-10pm so I am basically her primary care giver. We are currently seeing a counselor who is giving us some advice but our next appointment is 2 weeks away and I am feeling on the verge of a nervous breakdown from this constant stress. To be honest, I'd give just about anything to not have her in my house influencing my daughter, verbally abusing my husband and I and making my life miserable. Any comment or advice from someone in a similar situation would be much appreciated!!!
