Hilary Thayer Hamann said this quote

And loneliness. I should say something of loneliness. The panic, the sweeping hysteria that comes not when you are without others, but when you are without yourself, adrift. I should describe the filthy province of mind, the blighted district inside, the place so crowded you cannot raise the lids of your eyes. Your shoulders are drawn and your head has fallen and your chest is bruised by the constant assault of your heart. (p. 37)
