Ongoing vaginal (and other) symptoms - Was it something I ate?

I think I have had a yeast imbalance since I was a wee kid. Undiagnosed and unaddressed severe itchiness from age 6 maybe?

I have been on the candida diet for 4 months now, starting on the advice of a holistic nutritionist that root vegetable and quinoa would be good for me.... That did't go so well, so I started Candida Cleanse Phase 1 and have been on a regime just slightly less restricted than Phase 1 since April 26 (3 months)(www.candidacleanse.com)

I have been taking a different antifungal for a week at a time, rotating through 3 or 4 of them to hopefully outsmart my yeast and prevent it from getting more resilient.(On the advice of my MD I had been taking a Canesten Oral 1/month which made it so much worse!) Also took 1-2 Tbsp of diatomacious earth for about 2 months.

I still have varying degrees of obvious vaginal symptoms both with and without introducing new foods. Ex red peppers, rutabaga, coconut bread (basically eggs, baking powder and coconut flour).

Am I doing something wrong? Was it something I ate?
Should I go back to the insanity of phase 1?
Is this just the normal course of balancing a severe imbalance?
Can I go ahead and eat coconut bread and peppers and just stick with it for the long haul, continue with probiotics and antifungals and have faith that it will eventually get better?

I am so strong and so committed.

I am starting to lose it, though. Really!
