My Parents moved when I was 5, and divorced when I was 14, ever since I've moved about every 5 years or so - it's a restless life.
I've been bullied and beaten when before I was 5, bullied by a teacher in elementary school, and when I left there my parents divorced.
Depression probably has been with me since I was 6 or 7. Nothing matters, and I don't want to do anything. At the age of about 31 I got diagnosed with heavy depression and adhd (I'm female and probably authistic as well).
With 35 the last thing I hadn't tried yet was ketogenic diet. Within a Week my energy levels rose dramatically, and it took another year to pull it together, but my life is normal now (at 40 years old).
I haven't found a definitive answer, but my guess is that I've ruined my gut when I first moved. Can't digest plants and they ferment in the belly. It takes about 4 days to have effects. Any effect stays for a few days and then leaves when I go back to Meat and Butter.
Either that or the brain/immune system just connects carbs and veggies with violence/danger (mum used to beat me over food I didn't want to eat)
I've been to gastro enterologist - no diagnosis, allergy testing - no allergies, general practicioner - no diagnosis, psychologist - no diagnosis except for the depression and adhd part (which are much much lighter on a meat based diet)
