I feel you, and I've been there too. My personal opinion is that almost everybody in the Western world is suffering from some kind of indigestion. This was a view shared by German naturopaths back in the 19th century, like Arnold Ehret, though they've mostly been forgotten now. If you google "archonutrition", there's info floating around which could save and transform a lot of lives.
My advice would be to just not eat some days - that is, fast. And if you fill up on fruit, you'll lose weight in very little time. Only problem is that it'll also bring old illnesses up so you'll have periods of sickness, so go easy on yourself and for goodness sake don't take any kind of medication. Just follow your most natural instincts, you'll be fine.
