new to candidiasis

I just recently read of candidiasis and realized what has been wrong with me for so many years! I am having a difficult time right now because my symptoms are really bad. the infections has come out on my skin all over my skalp, my ear, my hands, and now its all over my face (including my lips). Lately I wake up unable to open my mouth very much. I am using tea tree oil many times a day, yet the infection is only getting worse.
Also, I'm struggling with the diet. I'm having a hard time learning what I can and can't eat and thinking of meal ideas.
Any advice or information would be great. I'm getting frustrated and a little depressed because my physical appearance is getting worse.
