you sound very desperate and I'm sorry you're feeling like that
I have been there before and I know what its like - the constant anxiety and then unfolding Depression was so overwhelming i often questioned the point of living like you're doing right now, but the one thing that is keeping me alive is knowing that there has to be SOME type of cure out there. I am currently on an herbal regimen that is supposed to clear me of my bad breath and Body Odor (an herbalist I saw told me that some of my internal organs arent functioning properly and these herbs are supposed to rev them up again), but I have only seen minimal results after two months now and it just seems that everything we try fails. have you tried a colonic cleanse? despite not seeing too much relief from my BO, it will flush you out and maybe get rid of some of the parasites that could be responsible for this.
good luck and take care..hang in there
