You become depressed because something was fucked when you were growing up. Might've been cold parents, might've been an absent parent, might've been abuse. Whatever the case, you don't have the same fucking sense of self-worth that comes naturally for other people.
When you're depressed, it's easy to be lazy. Not every lazy person is depressed, and the way you differentiate between the two is that a lazy person will at least ensure that their basic needs are met and they're fucking clean. When the lazy behavior sets in, you start thinking "wow, I'm a lazy piece of shit," which makes you more depressed, which makes you more lazy, etc.
