Firstly, sorry I said halitosis....I read you have bad breath, not health...
Anyway, I would highly suggest you get yourself to a holistic practitioner...a naturopath or the like. If the alopathic route didn't work (it doesn't sound like it did), you might find the help you're looking for. Meantime you might want to start a few things:
- yogurt or some other probiotic to make sure you have good flora in your intestine
- plenty of rest. If your adrenals are shot (it sounds like they might be), rest, peace and quiet, time in nature etc...are vital.
- Have some sort of practice for your nerves. Basic pranayama (ujjayi) will help calm your nervous system. Shamatha meditation will deepen it. A little of each every day will go a long way.
- recognize and accept it will take time to heal.
- diminish the obvious things like caffeine, sugar, white flour, meat, alcohol, tobacco etc....
- Slow down. Diminish electronics. Take walks, be with loved ones, quality time.
- contemplate what you feel would nourish your body, your heart/mind, and give yourself those things, a lot.
These are just some basic suggestions. Again, finding a holistic health practitioner and following their advice will probably go a long way for you.
Best wishes.
