It sounds like your high blood pressure could be due to some degree of kidney disease. That is something which I think that you should do all to prevent getting any worse! To do that you need to lower your homocysteine levels which requires optimizing methylation and working around any genetic polymorphisms which could be causing high homocysteine levels. Taking supplements which help lower homocysteine, listed in no particular order, such as P-5-P (vit b6), TriMethylGlycine (TMG), R-5-P (vit b2), magnesium, folate 5-methyltetrahydrofolate & B12 methylcobalmin. TMG should help your fatigue, you might need about 2-3 ml scoop if you buy TMG powder. I take that kind of quantity myself. However do not overdo it, check your tongue before you take any and again after an hour or two after taking it. If your fatigued you will have a thick tongue coating whereas after taking TMG the tongue coating should be a lot less. TMG has Yang energy something which is helpful for Yin diseases.

Taking serrapeptase, nattokinase or lumbrokinase might help clear and restore your circulation and help your kidneys. Taking any of those with a herb to direct towards the kidney might prove beneficial such as Tu Si Zi (Chinese Dodder seed) and Gou Qi Zi (wolfberry/Goji berries). There are herbs which warm the kidney which might also help. Vit K might also be beneficial.

What explains multiple food sensitivities much better than poor adrenals is Increased Intestinal Permeability Syndrome aka Leaky Gut. That is also what is causing your fatigue. Forget adrenal exhaustion because I very much doubt that you have it. It's a nonsense self diagnosis IMO with little basis in fact. Addisons disease is serious but fairly rare because it rarely gets that far, there is usually some adrenal function remaining even if the kidneys & nervous system becomes seriously affected by stress. I have some reduced adrenal function due to stress but it does not result in addisons disease or any detectable hypoadrenal function after my doctor referred me for an adrenal test due to tiredness/exhaustion. This can show in the iris of the eye at 6 o clock as a grey marking. The adrenals are at the top of this area just outside the autonomic nerve wreath which is the last to be affected by prolonged stress. Any greying of the kidney area indicates susceptibility to stress and high levels of cortisol as the body adapts to stress. The more that the kidney zone shows grey and the further into the zone that it goes, the higher the default cortisol level will be. BTW a grey marking does not indicate kidney problems! It is only the nervous system which is affected. Circulatory problems show near the outside of the iris in the circulatory zone as a discolouration, the more that goes inwards, the worse it is.
