Depression can take many different forms. And to be fair, we really do not know everything there is to know about it nor how to treat it.
But – someone can feel deeply depressed because of circumstances in their life that are indeed unhappy – this can be depression. It is not necessarily clinical depression, but it can certainly be called a depression.
The most serious forms of depression are chemically based. And from there, we start to create stronger neural pathways that help us stay in a depression. So – chemical and more.
