Candida/thrush

OK, so I'm just going to come out straight, I've had thrush since 12 years old, I'm now 19, so for the past 2 years I've used different methods to control it like coconut oil and oil of oregano. Anyway I thought it was gone and then my boyfriend got it and now I've got it really bad and nothings shifting it. As of tomorrow, I'm going on a candida diet, just wondered if anyone else is in my situation or could give me some advice?
