You are depressed….depression can cause all of the above things: spacyness, tiredness, binge eating, anxiety etc. Check with your doctor about the candida thing, because that doesnt sound right. I think that your mind may be constantly racing and you may be anxious which is causing a break down of the systems in your body. The best thing for you right now is to see a doctor. Im not a doctor, but I think that exercise and a good diet would help a lot to alleviate a lot of the symptoms that you are having. Good Luck.
