I do not feel qualified to give any sort of diagnosis but did want to share with you that candida overgowth and hypothyroidism share an almost identical list of symptoms.
I suffered severely with hypothyroidism for almost a year (to the point where I couldnt get out of my bed and if I made it out, I would have to sit and rest for half an hour in a chair before I could literally crawl to the bathroom), with 2 years leading up to that of all sorts of weird things happening to me that the doctors kept brushing off as depression, stress, "normal hormonal changes" when I was getting my period every 9 days....
Have you had your thyroid levels tested? If so and you came back in the normal range, then I would lean toward saying that you most likely have a candida overgrowth.
