I think wisedude is right in saying that it's just 14 yr old teen behavior. It seems worse in us ADDers.

Plus, she does have to learn. She could think that you'll never let here down. Just pick the right time so it's not important school dates where the fall could really hurt her.

I just wanted to add, you need to be careful about how you go about it. I had a friend who was AD|HD that I met when I was in high school. Her parents didn't medicate her as mine did nor do they really support her as my mom did me. In a way, their way of handling her was better as she is a better student than I ever have been.

Yet, they missed something because she blames everyone else and everything else for an problems in her life.

I took her in a few years ago. I wanted to help her grow and gave her the tools plus the space from her parents that she needed. I then because the reason for all her problems. I wasn't a nice person because I didn't treat her with respect. I think that was my fault on the respect side as maybe I didn't fulling figure out how my mom did it right with me. It was "you have to be cruel to be kind" kind of thing with her. As I had tried everything else I knew.

In the end we had to kick her out and I ended the friendship as I couldn't handle her anymore. It hurt that I had to do it but at the end of the day if she wasn't going to listen to the help I tried to give when it was respectful then it was lost.
