What is the difference between sadness and depression?

I think that depression has more of a numbness or emptiness to it, and sadness is more of a general feeling to it. When you're sad, you want to cry- And when you're depressed you feel more heavy and empty.

Mood: a low intensity emotional state; is duration can be hours or even days. An emotion last only seconds or hours.

Sure you might be sad but you can't feel it, in fact depression leaves you unable to feel emotions in some cases. You could say depression is an upgraded version of sadness.

Depression is continuation of sadness that can't be lifted, like atlas carrying the weight of whole world.

The difference between sadness and depression is that sadness is something that everyone experiences as a natural emotion, but depression is something which you feel down and sometimes you can't help it no matter if you have happy things in your life, it is to do with chemicals in the brain.
