I need a medical Sherlock Holmes to look at these test results

Hi all,

I have been running around in circles trying to fix my health issues for 5 years now. It feels like I'm chasing my tail. I wanted to put this up and ask for help in case anyone sees something I'm missing. I need a real Sherlock Holmes here.

It is clear to me that the problem is either an infection, auto-immune response or allergy response. Any ideas how to determine for sure which one it is?

What I know.

24 hour cortisol:
8am: 5 (range13-24)
Noon: 4 (range 5-10)
Afternoon: 2 (range 3-8)
10pm: 1 (range1-4)

Hormones:
Free Testosterone: 31 (range 60-135)
DHEA: 4 (range 3-10)
Progesterone: 39 (range 22-100)
SIgA: 5 (range 10-20)
Gliadin SIgA: <1 (positive >15)

Thyroid panel:
Free T4: 1.15 (range 0.7-2.0)
Free T3: 2.67 (range 2.6-5.4)
Reverse T3: .34 (range .09-.35)
TSH: 1.69 (range 0.3-5.0)

Blood work:

Eosinophils, lymphocytes and Basophils Consistently high (7 tests in 4+ years).
Neutrophils Consistently low (7 tests in 4+ years) Eosinophils
Potassium: 5 (range 3.5-5.1)
Calcium: 10.4 (8.1-10.4)
Magnesium: 2.2 (1.8-2.6)
Vit B12: 297 (211-911)

Gut/ parasite stool testing:

Candida: normal
E Coli: moderately elevated
All other worms/parasites: negative
Bifido and lactobacilii: slightly reduced
Bile acids: strongly reduced
Histamine: Strongly elevated
Calprotectin: Strongly elevated

Primary symptoms: massive fatigue, food allergies , blood Sugar imbalances, brain fog, memory problems, constipation, low basal body temp

What I need to fix:
-Gut and systemic inflammation
-Permeable membranes (leaky gut and brain)
-Low adrenal function
-Low thyroid function
-Multiple chemical sensitivites
-Brain oxygenation

Challenges:
-Very sensitive to most supplements including: Vit C, Vit B12 and B6, Magnesium, most adrenal adaptogens or glandulars, etc. Drinking water also consistantly makes me feel worse within seconds.
-Sensitive to most foods including severe sensitivity to gluten and sugar
-Fairly certain I have either a parasite, yeast infection or recurring allergic response but have always tested negative for all of these.
-Been on gut repairing diets for months at a time and seen very little improvement

What does help:
-Histamine free diet
-Eating fatty red meat
-Vit B5
-Enzymes, Ox Bile and Betain HCL with meals
