The brain feels the body and both are affected by the environment(e.g.: if your body is bad and you can't feel pleasure anymore, or it's lowered, how are you gonna have happy thoughts? Same applies to the environment, which is something that seems to be frequently ignored), not only that, stress is a chemical and it acts on both your body and your brain.. is this conclusion a surprise to anyone? Most of the comments here, people seem only capable of introjecting stuff as if the sole reason for stuff has gotta be personal issues(not saying this in a derrogatory manner) or a square diagnosis, this is absurd to me. Maybe it's cause I already came to the conclusion that I'm an ok mostly healthy animal plus gave up trying to fit the artificial into the natural(i.e.: I think our society is rotten. Also, how convenient it is that all problems must be seen as purely individual, huh?). History, classical thought -> good for the brain and body, maybe.
