Debatable. Depends how you channel outwards psychologically. People cope in different ways.
I don't think that is what depression is, best case like that would become high-functioning depression person.
Like high achievers can have depression, it seems like it can be some neurological or biological alternation after some events, like a depressed brain and a health brain looks very different, and it does not seem to be a emotion.
With all these said this is not the field I work in, I am just curious and I just read a bunch of related stuffs and watch some lectures on Youtube; but I personally think you might or might not be able to avoid depression when facing stressful events, but once you have depression, it is not something you can just snap out of.
Like you might still be able to carry on every daily tasks and achieve more, but the change in a neurological sense, would still screw up a lot of things, like waking up at 4 in the morning constantly.
Depression:
Some of glutamate and GABA connections between nerve cells break apart.
Emotions:
e.g.
Sadness is associated with increased activity of the right occipital lobe, the left insula, the left thalamus the amygdala and the hippocampus. The hippocampus is strongly linked with memory, and it makes sense that awareness of certain memories is associated with feeling sad.
When it comes to emotions, it turns out that there are regions in the brain, specifically in the limbic system, that are associated with each of the 6 main emotions.
