Candidas overgrowth

I was told I had it last year after it appears all over my skin. I asked my dermatologist what I can do to be rid of this they told me there was no fix you just have to live with it and occasionally use shampoo as a body wash. I am so tired all the time I never napped before but now I do. I never feel fully rested my doctor did a sleep study on me and found I rest well throughout the night. I have consistent UTI’s even though I take care of myself with a shower daily and I only drink water- Occasionally a coffee. I have achalasia as well as severe GERD- with diagnosed chronic constipation after a colonoscopy at 24. I’m only 26 now and I feel like I’m half alive. I have occasional severe insomnia with headaches. My joints are starting to hurt somewhat severely and I have been tested for arthritis due to my mother having sjrogens?? However you spell that autoimmune disease. I tested negative but I feel as though my joints are swelling. I have a see rate of 40 consistently and I’m scared. Does someone please have a remedy or help? My dermatologist said I had it but never explained which type or looked any further and I felt rather neglected in answers.
