We are never so defenseless against suffering as when we love, never so helplessly unhappy as when we have lost our loved object or its love.

Sigmund Freud

There is so much pain in the world, and most of these people keep theirs secret, rolling through agonizing lives in invisible wheelchairs, dressed in invisible bodycasts.

Andrew Solomon

Sadness is but a wall between two gardens.

Kahlil Gibran

The word 'happy' would lose its meaning if it were not balanced by sadness.

Carl Jung

Every single human being who is alive has felt this kind of pain, hopelessness, and loneliness at one time or another. We are all connected through this shared pain and struggle.

Leo Babauta

No matter how much suffering you went through, you never wanted to let go of those memories.

Haruki Murakami
