I have been mulling this over overnight. The thing I find so disturbing about this letter, is that if that was me, (and I can totally get and sympathise with how the author feels and how upset she is over her daughter's behaviour) anyway, if it was me, I would be writing a letter which went along the lines of:
Dear dd,
I know that at the moment you are finding life tough. I know that you are expressing that by directing all your unhappiness at me.
To be honest I find that hard. I am struggling with your anger at me all the time, and I find it hard that whatever I say you throw it back at me.
But I want you to know that no matter what you say, no matter how angry you get, I will still love you.
I love your intelligence, your passion, your ability to be gentle with younger kids. I love your smile and the way you flick your hair when you are happy.
But even on those horrible days when there aren't any smiles or gentleness to be seen, I still love you, because you are my daughter, and I will always love you, and I understand how hard it can be to be a teenager at times.
Before you roll your eyes at all this sentiment, I just want you to know this so that if you ever find yourself in a place where you need help, you will know that you can come to us, and we will be there.
In the meantime, could we call a bit of a truce? Could we start from the basis that I actually do want to help? How about we have lunch together and you can tell me what 3 things would make life better for you, and we can have a think about how we could make them possible.
love Mum.
