Is puberty toxic?

Does anyone know a good child psychiatrist in the Chicagoland area? I believe that the Angel is suffering from some kind of estrogen poisoning that is making her become nutty... seriously nutty. I say the sky in blue, she tells me it is green. I say study hard in school, she says I am stupid.

Her contrariness is driving me insane. Frankly, I blame Fun Daddy for spoiling her, but naturally, he accepts no responsibility. I guess it must be all those years of bad parenting I did alone.

But really, therapist recommendations would be appreciated.
