“Listen to the people who love you. Believe that they are worth living for even when you don't believe it. Seek out the memories depression takes away and project them into the future. Be brave; be strong; take your pills. Exercise because it's good for you even if every step weighs a thousand pounds. Eat when food itself disgusts you. Reason with yourself when you have lost your reason.”
― Andrew Solomon, The Noonday Demon: An Atlas of Depression

“Perhaps the greatest faculty our minds possess is the ability to cope with pain. Classic thinking teaches us of the four doors of the mind, which everyone moves through according to their need.

First is the door of sleep. Sleep offers us a retreat from the world and all its pain. Sleep marks passing time, giving us distance from the things that have hurt us. When a person is wounded they will often fall unconscious. Similarly, someone who hears traumatic news will often swoon or faint. This is the mind's way of protecting itself from pain by stepping through the first door.

Second is the door of forgetting. Some wounds are too deep to heal, or too deep to heal quickly. In addition, many memories are simply painful, and there is no healing to be done. The saying 'time heals all wounds' is false. Time heals most wounds. The rest are hidden behind this door.

Third is the door of madness. There are times when the mind is dealt such a blow it hides itself in insanity. While this may not seem beneficial, it is. There are times when reality is nothing but pain, and to escape that pain the mind must leave reality behind.

Last is the door of death. The final resort. Nothing can hurt us after we are dead, or so we have been told.”
― Patrick Rothfuss, The Name of the Wind

“The real hopeless victims of mental illness are to be found among those who appear to be most normal. "Many of them are normal because they are so well adjusted to our mode of existence, because their human voice has been silenced so early in their lives, that they do not even struggle or suffer or develop symptoms as the neurotic does." They are normal not in what may be called the absolute sense of the word; they are normal only in relation to a profoundly abnormal society. Their perfect adjustment to that abnormal society is a measure of their mental sickness. These millions of abnormally normal people, living without fuss in a society to which, if they were fully human beings, they ought not to be adjusted.”
― Aldous Huxley, Brave New World Revisited

“Bran thought about it. 'Can a man still be brave if he's afraid?'
'That is the only time a man can be brave,' his father told him.”
