Have you ever done a parasite cleanse? It sounds like you could have a parasite problem. I would gladly recommend Humaworm. There's a forum on this website where he'll answer any questions you might have. It's called "Ask Humaworm".
I'd also recommend a good multi-vitamin from a food source, because let's face it, our food just isn't what it used to be even if you're eating great. I would DEFINITELY look into the alkalizing your body as well. Basically you improve the inner terrain by adding calcium, magnesium, minerals, etc. in a form your body can absorb. There's another forum on this site called "Ask Moreless".
So, in conclusion, if I were you I would:
1. parasite Cleanse (I recommend Humaworm)
2. Get a good multi (I recommend Garden of Life Living Multi)
3. Alkalize my body (I recommend visiting the Ask Moreless forum and website)
