My life. What do I do?

Regular internal medicine say I'm fine, but I know I'm not. I've been looking into holistic medicine, but I recently came across homeopathy and I would be eternally grateful if I may be able to receive some help.

I started losing my hair since about 13-14 years old, thinning on top by a large amount ( I have to shave my head ) and my widows peak is pretty up there. But it stayed the same since 16. I'm 21 now. I also break out every time I eat something processed, have carbs/sugar, or anything that's not on the candida diet. A couple years back I was directed to a holistic nutritionist that said I have candida. I kept snooping around to find out that I might have parasites as well. I always stayed on a candida diet, which prevents me breaking out, but my skin looks bad even when it's clear; I have huge pores, my skin feels aged, I have scars from the acne I used to have when I had sugar, and I have some fine lines I'm not too proud about. Even then, if I accidentally eat something after a long time of keeping the diet, I break out; I'm just keeping the candida/parasites at bay but not getting rid of them. I couldn't buy any probiotics or any antifungals due to the expensiveness of it. I now also notice I have many tiny broken capillaries around my nose, under my lip where my soul patch is, and a couple under my eyes.

I read around, and it seems like candida/parasites are added problems to the bigger picture, maybe my entire organs are out of whack. My liver, bowels, kidneys, gallbladder, etc; they could be completely off.

So this is all background information to lead into my questions: What exactly do I do to completely have a healthy body? Can my skin get better? Is it possible to grow the hair I lost if it is due to some issues with what I mentioned above? Where do I start?

I would love if anyone can help me with any of these questions, it doesn't have to be all.

Thanks, it's good to always know more.
