the only thing that has really helped to control my moods and actually give me an idea of what it is like to be a stable person emotionally and mentally is doing a keto diet and focusing on quality, local, grass fed, and mostly raw meats and animal foods.
I suffered from manias, extreme anxiety and depression and eating disorders for 25 years. I am 30 now but my life has seriously been a vicious cycle of mania, weight loss, binging, alcoholism, weight gain, super depression, mania, car accidents, suicide attempts moving, being crazy, thinking I could fly, crashing, being a pot head, binge eating suicide attempts, and drinking, absolute misery......
all the while I was trying to eat healthfully, haha imagine that, because i knew that there was no way my misery was a product of the reality of my life(even though parts of my life have been shit, i can deal with a lot!) so i kept on with organic foods, then at 25 I stopped eating wheats, sugar, soy, beans, nuts, eggs and dairy... pretty much anything I was allergic to, my adrenals were crashed but doing this bolstered them up for 4 more years or insanity, ha! i stuck to pretty much whole foods though, still smoked pot, stopped drinking coffee, started taking some supplements, and AT LEAST felt i had a chance at being happy someday. i also lost my menstrual cycle at this age. slowly i have been weening myself out of these bad habits, with slip ups here an there, but the binge eating was still killer, even on paleo, i would be totally addicted to the ups and downs of my blood sugar, and felt like i was a skinny diabetic with exercise bullemia, when some major stress hit at this stage i was totally stopped in my tracks, full blown adrenal failure, gained 50 pounds and became a fat diabetic! realized i needed to cut the fucking carbs out once and for all, that i could no longer deal with blood sugar swings as much as i could no longer deal with these bouts of mania and depression.
taking carbs out of the equation, having a steady blood sugar and eating extremely nutrient dense foods has really helped. I also supplement with sam-e, coq10, multi, fish oils, b vitamins, iodine, mag and selenium. i got my menstrual cycle back two weeks into keto after its absence for 5 years. i am not totally healthy or where i want to be yet. but its only been 4 months, i feel like some deep seated problems are working their way out, lots of inflammation is gone for good, i don't really get excited over things, i am happy, i am calm, i can deal with life.
i will admit about once a month i get these little feelings, usually before bed, that "if i had a gun i would totally do it" little suicidal thoughts, and i have sat with those for a few days before i figured out my brain was just SUPER low on serotonin. so i have a carb up day if/when that shit hits, and eat a lot of popcorn. the next day i usually do a marathon of bike riding, but i don't go back to eating carbs, i get back on the keto horse and ride the good energy. its enough to bolster my brain for quite a while..
sorry this is a total mess of a wall of text, but there you go.
