Link between low white blood cell count and parasites/bacteria etc??

I am scheduled for my 4th HW cleanse.
I had been struggling with hormone issues (PMS but with fatigue) and had a blood test done. My white blood cell count was really low, my glucose was sort of low. My TSH was 2.3 (the same as when I was on thyroid meds, but I do not tolerate thyroid anything, another autoimmune thing??) However, I do not have antibodies in the blood (dr says it is due to the low WBC count)
My ND says it is autoimmune, and has started treating it.

However, I am wondering what is going on. I ask the "why" would I have autoimmune? (which I have suspected for a while). As I understand a low WBC is caused by medications (which I do not take), another thing that can cause it is a chronic infection, which bought me back to the parasites/bacteria etc.

Is anyone else dealing with this? What do you do?

What does RG think of this?
