I actually believe, like people have already stated here, that is comes from both experience and a chemical in balance.
I, however, believe it starts with the negative experience and the sad feeling it creates, then sends unpleasant and unwanted chemicals through the body, in greater quantity. Causing a literal physical reaction, as well as a psychological one.
Almost like the negative thought activates this realise somehow. Somehow wrongly re-sets the brain. That's just what I've physically felt through my own body. Which could explain these studies that show higher numbers of certain chemicals in depressed people etc. Like an acid or something. Just need to check the timeline, perhaps. Would be interesting.
In a similar way to how stress can cause issues with other organs in the body.
Just a thought. Not saying some aren't born genetically pre-disposed.
