I would start by immediately taking her off of all cow's milk products (read the labels to be sure). And then I'd stop or at least minimize any other unhealthy foods she's been eating (white flour, sugar, corn syrup, processed foods). Especially if she is at all overweight, but even if she isn't. (if she is overweight, changing her diet should help with that too, as well as exercise). And if you still don't see a difference, I'd elminate other common allergens (wheat, soy, corn. Offer her lots of a variety of fresh organic (preferably raw) fruits and vegetables. Of course she may protest if you take away her comfort foods, which can be quite addicting, so she will need extra love and affection. Of course it would be best for your whole family to change your diet - this could be a blessing in disguise for all of you!
