Candida and feeling weird

Hi guys!

I went raw like 3 years ago, it lasted 3 months but i noticed that bananas and high glycemic fruits makes my tongue drier and more white in my tongue.

I was high fruit, no fat no protein at all.

Im here now because i want to resolve rheumathoid arthitis, dry mouth and thin layer of white coat inmy tongue, stomach pain every day, low immune system 2 fevers and diarrhea in the last 2 years and fat cravings. 

I think i have candida.So how to healed, where to start, i cant eat enough because il have colitis and at the end of the week eating fully raw makes it way too expensive. 

Please help, hear all of you!
