Hey! I'm sorry to hear about your daughter developing panic attacks so early, but it's not really that uncommon. It seems that the anxiety disorders are the mental illnesses that are most often diagnosed in childhood. I don't think that age 9 is extremely early- I can remember having panic attacks since I was at least five and possibly even since three, so don't feel bad! I don't have panic disorder, though. My panic attacks are due to OCD, GAD, and phobias- in a certain situation, I know that I'll have a panic attack; they're not unexpected without a source of definite worry like your daughter's having. I agree with the others' advice about taking her to see someone. No child should have to deal with this in their academic life. Believe me, as someone who's been having panic attacks multiple times a day during my whole time that I've been in school (just graduated high school), it's not fun, but being physically sick on every single test day or before every single presentation has just become second nature to me. It might sound like I just have "test anxiety," but it's much worse than that. I get panic attacks in other situations- I'm actually having a minor one right now! LOL! For some reason, going on the computer has always made me nervous...
It's best to treat your daughter early so she can live her life without fear. The problem with me is that I didn't know what I experienced was a panic attack until age 16, and now if I'm in a situation where I should have a panic attack and I don't (such as before a test), I actually worry about not worrying enough!
I honestly don't know how I'd react without them because they've been such a miserable part of my life for sooo long. You should be proud that you were able to catch her symptoms so early on before her parasympathetic nervous system becomes non-existent, like mine... God bless!
