H202 therapy and leaky gut/inflamed intestines

I have leaky gut, H.pylori, system candida (I think) and I'm sure parasites. My stomach and intestines are so sensitive right night but I've ordered food grade H202 3% to do the oxygen therapy. I'm really scared that it will make my intestines more painful and sensitive but I need to get rid of the bacteria, yeast and parasites before I can heal my gut. I have high acid in my body right now and I smell so bad of fish and human poo? Which makes me believe worms of some sort too. Should you risk H202 therapy? Or will it help my gut and intestines? I'm on my last day of Antibiotics for the H.pylori, which haven't helped one bit but made me smell so much more worse, like this smell is unreal, its so strong my neighbours are complaining and quite threatening! My breath is more rancid than ever too.
