I have an sd who is a complete nightmare to deal with. At first, I felt sorry for her because her mom used some pretty heavy parental alienation on her and her sister which ended up with us winning majority custody, but she still continues. My sd who is 17 is a completely hateful, negative, mini version of her mom now. My dh has done everything he can think of to try to combat this bad path that she is on but each year it just gets worse.  Her negative attenion seeking behavior continues to escalate.
