hi Scotty. maybe i can help.
i've been lurking around here for a while and may as well dive in for this one.
i think i might know where you're coming from regarding your problem. i started an experiment involving mostly meat and fat with bone broths (WAPF's purported miracle elixer... hah!). the pounding heart and vibrating anxiety (especially at night) that i developed within about 4-5 months left me in much the same state as you. haggard and burnt out.
regarding broth, it seems that some have bad reactions to isolated amino acids (in my case, tyrosine and other amino acid supplements, and the cursed glutamic acid. a pox on WAPF's house!
). bad hydrolysation effects for some of us might be another reason to go mainly raw.
the crap i went through only stopped when i quit eating so much fat and protein
and those stupid bone broths. if i ate one or the other, nothing changed. i don't do well on a high fat or fat/protein diet. my backpacking, cycling and mountaineering suffered big time.
everyone is different, and i don't make unequivocal statements about what others should eat. some do well eating only animal products. good on 'em. but maybe you are thinking too much about diet, and worrying, like some others, about starch, fruit and phytotoxins in veggies etc. maybe one who doesn't have problems with specific foods or macronutrients should simply eat more instinctively, in a general "paleo" context? i don't know...
...so this is my diet (trust me; i've done 'em all, from vegan, to down the line carnivory, to everything in-between):
morning: fruit (yes, those candy bars on trees that Harris vilifies. nonsense). 2 bananas, some pineapple or melon or whatever else moves the spirit.
lunch: meat to satisfaction, some steamed roots (carrots, beets, parsnips, etc.).
home from work: a big green salad with olive oil, cider vinegar, some chopped up meat in it, some berries, and whatever the hell else i feel like eating (in a general paleo context).
nothing written in stone, this is just a general day.
macronutrients seem to fluctuate, with fat hanging around the 50% range (gms), though i don't give a shit about it.
so, i hope this helps. good luck, and don't think so much
