Sylvia Plath said this quote

I am drowning in negativism, self-hate, doubt, madness - and even I am not strong enough to deny the routine, the rote, to simplify. No, I go plodding on, afraid that the blank hell in back of my eyes will break through, spewing forth like a dark pestilence; afraid that the disease which eats away the pith of my body with merciless impersonality will break forth in obvious sores and warts, screaming Traitor, sinner, imposter.
