Parasite question

From last 1 year and 7 months with decreasing the mercury from my body I feel really great benefits from chelation and nutritional balancing program. My crohn is almost gone but adrenals are exhausted due to chelation.
The last month I feel a regression in my health...

Recently I noticed this in my stools and I suppose it's some type of worm (picture is not for squeamish people):

I don't know how to deal right now. Is there any accurate examinations I can do? I'm tired of all these things - metals, toxins, parasites... please tell me what I can do now...
