I am really sorry to hear about your struggle. I am not a medical expert but I have had some personal experiences that made me wonder if many of your daughters’ problems were food related. Starting this year, I switched to a gluten free and dairy free diet because I discovered foods containing gluten and dairy make me sick, including messing up with my brain and making it hard for me to stay calm and focused. I saw similar effects on my daughters. You should do your own research (a friend told me about the Grain Brain book). A good way to find out is to remove gluten and dairy from her diet for 2-4 weeks and see if the issues improve. If it is too hard to remove both, maybe start with gluten. Best luck!
