This is just very common. I am worried about my daughter. She tries but she sometimes says she cannot. We are going to have a meeting with the school, counseler and her doctor and see what can be done about her absence at school this year. Oh I am so worried.
I get the same way when asked about my homework. I don't know if she feels the same way I do, but I generally feel like those kinds of questions show a lack of trust and they make me feel like if I am doing the work, my mom gets "credit" for it, because she reminded me instead of me getting a chance to show my responsibility. As I said, I have no idea what's going on with her, emotionally, because I'm all the way on the other side of the internet, but if she'll participate you may want to try and talk about -why- she gets so twitchy about having school work brought up. That is, if you haven't already asked about it.
I know it was a while back, but I just wanted to say that you get epic points for -not- sending your daughter to boot camp when that counselor recommended that you do so. Far too many parents fall into th trap of putting their kids in places like that, and are unaware of how much damage they are doing until the ( usually, broken and traumatized) child is returned home.
