Norah Vincent said this quote
“ I was always asking myself why. Why am I feeling this? Thinking that if I knew the cause I could find the cure. But of course there was no reasonable why, at least not in the present. I was awash in an accumulation of past feelings and future dreads, all similar, at least as far as my brain was concerned, and so, lumped together as one. But nobody can handle a lifetime of experience in one moment. That's why depression crushes you. ”
