Dd is 12, she has some mildish SN and she has been horrendous for the last three years.
Beyond rude, argues constantly, pinches and pushes me, screams in my face, breaks things in the house, contradicts. me when I'm talking to work/friends/family on the phone. Won''t leave the dog alone, ignores everything I say, will blatently sit and turn her back to me when I've asked her to do something.
She used to be such a lovely, polite, well mannered girl. Now she's awful. Even my Dad who never tells her off is getting annoyed.
Even days out just for her to special places are ruined by her, nothing is good enough for her.
To make it worse she never is in her room, she's always a foot away from me. I have no space. She is always in my face. She also gets angry if I punish her or simply angry at me for being upset or annoyed that she has been nasty to me 
I have asked nicely, told her off, shouted, taken away gadgets, grounded her, praised the good etc
Nothing makes any difference, I'm tired and not well myself and I'm just so very tired and sad.
