it sounds like you have a lot of dysbiosis. I would be stopping the DE and oregano oil and instead doing black walnut WHILE taking NAC, chlorella and liver support (obviously check with your doctor before taking these supplements as these may not be appropriate for you).

Also I do not recommend KETO diet for too long as it can overburden the liver and can make you more acidic. Try eating a lot more alkaline foods and veggies and instead of so much fat, eat more protein and complex carbs (squash, buckwheat, berries, etc).
