I've also been told that trauma for the stomach can effect the emotional state, and I can personally attest to feeling distressed, then eating a good sized meal and feeling better afterwords; Also connecting with fast food and eating disorders.
But this could also be an old wives tale, and I'm suffering from a placebo effect.
I'm a fifteen year-old high school student, Junior, and ended up finding this through the Harry Potter & MOR story, which I thought would be a lot less common to people. Generally I think I'm not that rational of a person, I operate mostly on reaction and violence, and instinctively think of things like 'messages' and such when I have some bad luck; but, I've also found some altruistic passion in me, and I've done all of this self observation which seems contradictory, but I think that's all a rationalization to make me a better person. I also have some odd moods, which split between talking like this, when usually I can't like this at all.
I'd say something about my age group but I can't think of anything that doesn't sound like hypocrisy, so I think I'll cut this off here.
