Oh, I'm so glad I found this thread. My DS (who was diagnosed with ADHD and attachment disorder some years ago) is now 13½ years old and is totally obnoxious!! While I love him dearly, I don't much like him at the moment.
The posts from Willow65 and Rainbowlady sound so familiar. I know it's not much - but I really understand how you're feeling - I'm there too.
On the plus side, my friends and the school, all say that DS is polite, well spoken and nice to them. It's just when he's home that he becomes so awful. He's rude, he swears at us, he hates us, he throws things, he's taken to picking up objects to threaten us with. And yet when he's in a good mood - he's loving, kind, hugs us, spends time with us.
I have to admit that I'm not enjoying the teenage years so far. I hope that DS is going to be one of the ones who grows out of it sooner rather than later. I can hope - it makes life a bit more bareable.
I know that both DH and are are good parents, but it's so hard when you have to cope with such behaviour in your DS. We have firm rules and stick to them too (perhaps that's the problem). Anyway, I suppose this thread has made me feel less alone. Thanks for that.
