I've actually realized that when i was a teenager I trained myself to ignore hunger pains. I have 3 younger siblings that I more or less raised and honestly there wasn't always enough to eat in our house. I would never even think to take food out of my siblings mouths so that i could eat, So I'd make them something to eat and I would go without; after all I was older I could handle going without.So now that I'm older I actually forget to eat and will go all day without eating. Until I start shaking so bad I can't walk or write or type. But I've noticed that even when I do realize I'm hungry I gave no desire to eat. I honestly feel like there are better things I could be doing with my time.
