I'm glad that what someone on this board posted has given you a spark of hope. Reading from your list of symptoms, I would encourage you to have an endocrinologist take a look at your thyroid hormone levels. Many of the symptoms you list sound like your thyroid might be doing a poor job and needs some help. Under those circumstances, it wouldn't be surprising to have candida symptoms, as an underactive thyroid usually accompanies candida. Some people with severe Depression have suddenly found life when their thyroid problems were adressed.
Yes, it takes commmitment, but there is never just one magic bullet to take care of all your health problems, but certainly you can overcome anything when you set your mind.
You sound like a really special person by the way , very sensitive and articulate for your tender age.
