Is there a difference between "depressive" and "depressing"?

Solution 1:

Depressive mood and depressing scene.

The state of being depressed is depressive, but things that provoke depression are depressing.

I'm depressed.

I'm in a depressive mood.

I've seen a depressing video.

Solution 2:

"Depressive" can be an adjective or a noun; as an adjective I've only ever seen it in the phrase "depressive disorder".

As a noun, "depressive" can mean:

• some intangible thing that is depressing (such as news)
• a substance that has the effect of depressing mood or function: alcohol is a well-known depressive
• a person who suffers from depression
