Pinworms are back, please help!

I had a battle with threadworms/pinworms about 7 months ago for the first time, took Reeses(Pyrantel Pamoate)2 doses 2 weeks apart, along with Green Black-Walnut Hull/ Wormwood tincture (2xdroppers day)and low Sugar diet. It seemed to whip them and I thought I was free, back to my routine. Well they've returned with a vengeance 7 months later, crawling all over me at night, in anus, nose and ears. Add to that bad constipation, inflamed bowel, candida overgrowth, Depression and anxiety, insomnia and suicidal thoughts. These are driving me crazy and I spend most of my time either obsessing about them, cleaning the place, or becoming some sort of Howard Hughes shut-in. I live with my girlfiend in a separate bed now, and she has no symptoms at all. I've also have vitreal floaters in my eyes for a long time now, and can actually see organisms and food particles in my vision. and am starting to believe that maybe my digestive tract is compromised to the point that parasites and Systemic mutated Candida have entered my bloodstream and are migrating around my body. I am on a daily protocol of 2x droppers of the Green Black-Walnut Hull/ Wormwood tincture again, also 10 drops of kelp Iodine daily, and 5-7 drops of wild oregano oil daily. I also take crushed clove powder once daily with cayenne and cinnamon with a full glass of water. And for nose I am taking Nutribiotic nasal spray with grapefruit seed extract- I think that the anal itching has lessened a little but sometimes at night I can still feel them all over me, can almost feel the larvae/nymphs moving around my eyes, ears, nose and other random body parts. I have a constant stream of mucus in back of nasals/throat that I am always swallowing and think maybe they've established a foothold up there and are perpetuating the life cycle that way, regardless of how much I clean for eggs. My diet is almost Sugar free, very low carb, lots of water, vegetables, and garlic. Am I on the right track? Sometimes i have this feeling of urgency like I could be doing more, but I dont want to be so stressed out that I am compromising my immune system...Should i continue this routine or contact a parasitologist/infectious disease specialist? The suicidal thoughts are starting to worry me,...I cant have these for the rest of my life..Any replies appreciated- Tweet
