Funny, huh, how a small tiny little thing located in your limbic system, the middle part of your brain, called f e e l i n g can make your body physiology not functioning normally?
My appetite has been switching from hungry-not hungry-super hungry-i can ear nothing for 2 days from time to time. Sometimes my heart skips a beat or two, or slowing down it beats, or aching. One time I feel like the happiest person on earth, and another time I feel like crying a river.
But suddenly I remember, one of the hypothesis how the circuit of Papez works, (pardon me I forgot whom invented the hypothesis),
"smile, then you'll be happy ; cry, then sadness is what you'll get"
