"You made a mistake, you were a bit impertinent accidentally and sadly like all too many people caught out being ill-mannered you are blaming the other person."
Many people are sensitive about others knowing their age. If you didn't know that your partner felt this way and mentioned their age casually in the course of a conversation with someone else, and were overheard and remonstrated with, would you also say that you had been 'ill mannered' and 'impertinent'?
"in order to come to a point where you stop perceiving your Ds behaviour as abusive"
If she was a teenage boy of 16, just 3 years older, and was following me around the house screaming and threatening me, telling me I was old and pathetic, I'm sure you would have no problem describing this behaviour as 'abuse'. It is abusive to threaten and insult someone because they've not bought you crisps, or allowed you to go out with your friends, or have asked you to tidy your room. She screams and swears at my asd six year old and calls him 'dickhead'. That's abusive.
I love dd but her behaviour is hideous at the moment. And is damaging the family. It's the truth, however unpalatable and sad.
(and before anyone asks - yes we do use sanctions. Many. Often. They don't work. She has lost her phone, her computer, her pocket money, had early bedtimes and been grounded for months at a time and she is still obstructive and rude).
But yes - I know I need to get to grips with my depression because it's stopping me finding a way through the emotional storm that's going on at home, and preventing me from fighting effectively for the support that my son needs, and isn't getting, at school.
"Stop being a victim and think about the impact your actions are having on your family"
Sorry - what 'actions'? All I do is try to keep peace between my children, help them with their school work, praise the good things they do, try to guide them away from destructive behaviours, and provide a stable and secure home for them. But I'm not a robot and sometimes having two exceptionally difficult children grinds me down. It would grind anyone down.
