severe case of allergies and eczema..plz help

MY 13 yrs old daughter has a severe case of eczema and allergies. i breasfed her for an year. i only stopped breastfeeding her because we got her tested for food allergies and it turned out that she has multiple food allergies along with milk and soy allergy. her doctor said that its not healthy for me to eliminate so many things from my diet so its best for me and her to give up breastfeeding and feed her nutramigen which is especially designed for allergic babies. Her multiple food allergies of a kind not seen yet by so many Allergists. To name a few, she is allergic to wheat, soymilk, cow milk, goat milk, peanuts (and all foods of the legume family), tree nuts, shellfish and other seafoods, chicken, beef, egg, squash, cantaloupe, banana, strawberry, citrus, etc. To be honest, there is very little to feed her.her allergies are so severe that everytime she gets allergic we have to call paramatics. she gets bumps all over her face and body, her voice gets all husky, she has trouble breathing, she scratch till she bleeds and in some cases she pass out for few seconds. For her eczema we use 2.5% hydrocrotosone and alot of aquaphore. i also tried different oils but they dont make any difference. i even bathe her with mostirizure instead of using any soaps for her. we dont use any perfume based products for her. i always have to dress her so that every part of her body is covered otherwise she itches every chance she gets.. i m in a need of desperate help...every piece of advice will be greatly appreciated.
thanks
