Histamine

It appears I now have gotten very sensitive to histamines in foods,which is probably caused&worsened tenfold by the current humid warm weather&sun. Apparently my metabolism gets very stressed by this weather and doesn’t function properly anymore.
It is what caused the fluid bump/blister and worsens the fluid retention,red skin,lots of itching,moodswings and constipation.Had a terrible headache yesterday that only became worse no matter what I did or didn’t eat&drank Especially the swelling and the constipation is bad and I do not know anymore what to do.Bc if I’m constipated food stays too long in the gut and creates even more toxins/histamines or in other words stress.
In the evening&nigth when it starts to cool down a bit and when it’s dark,I sometimes am able to go to the toilet,my moods/anxiety/anger or whatever vansh and I become more calm and positive/hopeful again.

According to Ray Peat having these kind of allergies (not handling weather well) is a sign of low thyroid.,but I wonder if it’s low thyroid leading to these sensitivities or the other way round? The weather inhibiting proper thyroid function?
I’d been,as long as I can remember,sensitive to heavy sunligth and looking back now notice the pattern that during July&August for the last couple of years during this humid weather I for no reason can turn into a raging angerball sometimes wanting to punch people in the face….which is totally not me!
But,in all those years, I’ve never experienced such severe symptoms as now….I really don’t know what to do anymore,bc it basically also ruins the kinda jobs I wanted/searchig for.
