Bio-chemically, major depression is a mild but permanent drug withdrawal.
>>9242168There's a mind/body connection that we're just now starting to understand. Thoughts can effect the biochemistry of our brains, and the biochemistry of our brains can effect our thoughts. Because of the way this works a feedback loop can sometimes occur forcing their thoughts to make them depressed and then their body makes them even more depressed and so on and so on.... But this is only one instance. Depression can occur in other ways for instance if biochemically the physical brain becomes depressed, a person may try to "think them selves better" and they may be able to cope or may not. Coping is a learned skill. I think you get better at it with time, but depressed people often don't even want to try to learn to cope due to their illness, and others may try to cope, but simply don't know how and have no success with it.
