Can anyone tell me if this is hereditary? Her cousin has been diagnosed and I am just not sure. I have downloaded/printed info off the internet and everything fits. She is going to Psychiatrist for first time soon and am not sure if I should bring it up at the first appointment. Her dad and I divorced, and it wasn't ugly but wasn't pretty either. He was emotionally/verbally abusing all of us for years. He still has a HOLD on the girls, but the 10yr old seems to take things more personally. She hasn't hurt anyone but she gets very angry at the drop of a hat. Temper tantrams and rages. (She hit me in the chest last night at Kmart cuz she couldn't have a new lip gloss) She dumped apple juice all over my bed last night cuz she was angry. She does things when she wants and never does what I ask. Her grades are on a downward spiral and she HATES her teacher. She has always been very temperamental, but I always chalked it up to the red hair. I am beginning to have second thoughts that it is more than that. I am just at my wits end with her. I think that somehow my divorcing her dad has made her this way. But maybe it was staying in the marriage and subjecting the kids to the abuse did this. Either way I think its my fault. Any thoughts, comments, suggestions?
