No one wants to be depressed. Being depressed is not fun. It is NOT the bittersweet sadness that makes you just want to curl up under a heavy blanket and watch TV all day long. It is the agonizing cement block that slams on top of you and doesn't let you up, doesn't let you breathe.
Being depressed is NOT mind over matter. It isn't just getting up and looking at the bright side of things because when you are depressed, you can do those things. It just doesn't work.
Being depressed is NOT feeling sad. Being depressed is NOT feeling. At all.
