WOW, can I just say that I am so sorry for everything that you are going through with your daughter. I am thinking that her diagnosis may be off key. It sounds more like she has a mood disorder. I am NO doctor but from the kids that I have been around that sounds to me more of a mood inbalance. I would want to try her on something like Lexipro or have her re-evaluated. I know that you said that money was tight and honey do I understand that I am the mother of 4 children, I'm lucky enough to be married and have my mother living here with me she watches the children for me so that I can work but I've been out of work for over a year due to a work related injury and I am now looking for work again because I have to change careers anyway not the point the point is I understand a tight financial situation. Do you have insurance? to where she could be re-evaluated and possibly re-diagnosed? Sounds like a little more than ADHD??? I hope that you figure out what's going on and are able to keep your sanity in the process!! Good luck.
Your daughter needs some help and someone to talk to to find out what is going on, get her some help.
