I know how you feel, but not too strict your diet if it is make you too depress. ( I feel depress sometime if I cannot eat what ever I want, but I think about diabetics patients, they cannot eat all food like us for life long, but for up who know, may be we will be ok one day)
As for me I believe what Jake said that Candida overgrowth is dut to poor digestion.
So please try to digest your food by taking HCl, Digestive enzyme, colon clean ( by psyllium or with enema ), liver clean, with a lot of different kinds of probiotics. (take Kegir or take Saccharomyces boulardii if it is not included in your probiotics, I think it is included in primal defence ), and take Advanced Antioxidant formula from Solgar plus candida diet.
I cannot say it will cure your illness, but you may feel a lot of relieve and we will fine a proper treatment one day.
