I think suspect I have had candida pretty much my whole life made worse by taking Antibiotics for a yeast infection when I was 14...Since adrenal fatigue and candida are pretty closely intertwined I suspect if I do have it as well that it also started or worsened around that time...When I was a kid I did have more energy and more heat/sun tolerance but as soon as I hit puberty that seems when ALL my problems started!
