Have you ever tried any antifungals? Some people say that you cannot get rid of candida only following the diet etc..It will only reduce the amount of candida in your body, but not killing it.
I can not be sure, but I guess that the bloating could be caused by candida, or dysbiosis.
For the leaking gut, try also the horsetail tea, it contains plenty of silica, that helps your gut to get better..
