Would a change of behavior/lifestyle change the depression? Yes. Clearly I disagree with others here. The problem is that it's a vicious circle so it's difficult to change your behavior/lifestyle. But if you can, maybe with external help, it surely helps except maybe in very hard cases. By the way, I'm not sure the term clinical is being used correctly in other comments. Could someone with relevant knowledge confirm? The worst obstacle to break the circle are negative thoughts, that hide where the exits from the labyrinth are.
