You take words too literally. What is the opposite of containing or managing internal emotions? I'll answer for you.

"Expressing them with a particular action relating to the emotion."

The emotions never went anywhere, they are still contained internally whether you yell because you're angry or not, so your example doesn't work. You could say some technical babble about how the emotion has been outwardly expressed into the universe, but it hasn't. What was expressed was sounds or words or movement, which can then be interpreted by others, who would get a general idea of the emotion you tried to convey but not the actual emotion. I'm not saying you think emotions can be truly conveyed, I'm just saying this in case you decide to take the argument that way.

Anyway, the emotions aren't contained in the first place. Forget containing, it's nothing. The emotions are just there, they exist in the universe as neurochemicals and whatever else.
