Wow,
To be honest it sounds like you've had some pretty rough patches. Times are tough, but just hang in there. There are always ups and downs, and you have a family that you really need to be there for.
I see that you're trying your absolute best to be healthy, like avoiding fumes as much as you can. Try following Kelly Stahl's candida recipe book, and the candida treatment book. I know you love coffee, but you're going to need to cut back on that as well as sugars.
You're going to need to fix your diet, please use kelly stahl's books for ideas. You cannot cook stir fry every day either. What kind of oil are you using to cook with it? You can eat many vegetables raw, yes it doesn't taste good, but it's best for you. Good luck!
