Depression.
It comes in all forms and sizes. Just browse your facebook wall. Some will keep ranting about whatever crap they are going through - cursing, complaining, fussing about the inequalities of whatever.
For others, well, some just like to sleep all day long, wishing that everything will be alright when they finally wake up. But they never do.
For many others still, they keep buried in work. Tons and tons of work. Until their life is literally sucked out from their veins (Caffeine replaced their red blood cells, perhaps?) Exhausting every bit of energy their already tired bodies could endure, so that they would be too tired to think of their problems. Or to even feel anything.
