“Depression is the most unpleasant thing I have ever experienced. . . . It is that absence of being able to envisage that you will ever be cheerful again. The absence of hope. That very deadened feeling, which is so very different from feeling sad. Sad hurts but it's a healthy feeling. It is a necessary thing to feel. Depression is very different.”

“It’s so difficult to describe depression to someone who’s never been there, because it’s not sadness. I know sadness. Sadness is to cry and to feel. But it’s that cold absence of feeling— that really hollowed-out feeling.”

“Depression isn't just being a bit sad. It's feeling nothing. It's not wanting to be alive anymore.”

“That’s the thing I want to make clear about depression: It’s got nothing at all to do with life. In the course of life, there is sadness and pain and sorror, all of which, in their right time and season, are normal—unpleasant, but normal. Depression is an altogether different zone because it involves a complete absence: absence of affect, absence of feeling, absence of response, absence of interest. The pain you feel in the course of a major clinical depression is an attempt on nature’s part (nature, after all, abhors a vacuum) to fill up the empty space. But for all intents and purposes, the deeply depressed are just the walking, waking dead.”

“Well, obviously, she's feeling very sad, because of Cedric dying. Then I expect she's feeling confused because she liked Cedric and now she likes Harry, and she can't work out who she likes best. Then she'll be feeling guilty, thinking it's an insult to Cedric's memory to be kissing Harry at all, and she'll be worrying about what everyone else might say about her if she starts going out with Harry. And she probably can't work out what her feelings towards Harry are anyway, because he was the one who was with Cedric when Cedric died, so that's all very mixed up and painful. Oh, and she's afraid she's going to be thrown off the Ravenclaw Quidditch team because she's flying so badly." A slightly stunned silence greeted the end of this speech, then Ron said, "One person can't feel all that at once, they'd explode.”

“They simply had very different notions of what ought to take up most space in life.”

“I am very frustrated by fear of imagination, I don’t think that’s healthy.”
