Sounds like classic morgellons.
But I guess you're happy it's probably not disseminated strongyloides...(bitter laugh).
First, STOP taking a ton of stuff for the time being.
You're allowing the parasite to become resistant, and that's very bad.
Next, take care of what seems to be a fairly severe magnesium deficiency, probably caused by intestinal malabsorption, which can be exacerbated by the drugs you were taking. There are many details to mag supplementation...so educate yourself, don't just start popping supplements. Epsom Salt baths are the best.
That will make many of your symptoms less severe; many will vanish comletely, and magnesium has the advantage of calming down a reactive nervous system.
Start educating yourself, and take it slow.
