i have no remedy suggestions...
but i just want to offer my moral support.
my 11 year old had her first visitor 3 months ago and all of the sudden, i feel like i have no idea what i am doing as a parent anymore. she gets headaches with the cramps but she doesn't have full blown migraines. for ten years, she was the perfect daughter. sweet. loving. intelligent and organized... now, she has these devil-spawn moments that truly frustrate me.
but this thread is about your situation... good luck.
