Hey Lelouch. Yes, keeping ourselves busy serves as a distraction. Which mean that while you are engaged and occupied with other activities, you literally spend less time ruminating about depressive or negative content. The more time we spend on depressive cognitions, the more negative our mood will be, which in turn affect our behavior and how we respond to the environment (most probably in a negative way). Then, the behavior outcomes which is negative again affects cognition, and so we see a vicious circle developing. Eventually, as people become gradually depressed over time, they develop what is referred to as the cognitive triad: negative view of the world, negative view of one's expectations and future, and 3rdly, negative view of the self. Everything that I've explained up till now, can and will occur becomes of what is referred to as a depressogenic schema or dysfunctional beliefs and assumptions that you may have internalized in your earlier years. So these underlying dysfunctional assumptions actually cause you to develop a vulnerability (diatheses) for depressive symptoms. However this can only happen in the presence of a relevant and severe enough stressor or life event. I'm sure this makes sense to you. Take your text or thread for instance, its clear tht dysfunctional assumptions are present. To further understand this please read up on fallacious or faulty information processing. Examples of this is dichatomous thinking, selective abstraction, labeling and mislabeling, magnification and minimization, arbitrary inferences, etc ...i hope I recalled these examples of faulty information processing correctly. Nonetheless, do search the internet more on information processing and possible examples of each, so that you can have a good understanding. All that I have explained is called Aaron Beck's cognitive model of depression. So, correct your underlying dysfunctional assumptions and beliefs, and you don't become prone to depressive affect.
