"The whole conviction of my life now rests upon the belief that loneliness, far from being a rare and curious phenomenon, peculiar to myself and to a few other solitary men, is the central and inevitable fact of human existence."
"One may have a blazing hearth in one's soul, and yet no one ever comes to sit by it."
"I never found a companion that was so companionable as solitude and loneliness."
"The worst loneliness is not to be comfortable with yourself."
"To dare to live alone is the rarest courage; since there are many who had rather meet their bitterest enemy in the field, than their own hearts in their closet."
"Who knows what true loneliness is -- not the conventional word but the naked terror? To the lonely themselves it wears a mask. The most miserable outcast hugs some memory or some illusion."
"With some people solitariness is an escape not from others but from themselves. For they see in the eyes of others only a reflection of themselves."
"There is no greater sorrow than to recall in misery the time when we were happy."
"I know the night is not the same as the day: that all things are different, that the things of the night cannot be explained in the day, because they do not then exist, and the night can be a dreadful time for lonely people once their loneliness has started."
"It is loneliness that makes the loudest noise. This is true of men as of dogs."
"Loneliness the clearest of crystal insight into your own soul, its the fear of one's own self that haunts the lonely."
"The loneliest it gets is when the wind begins to chill and when I sit atop of your old street, the church top brings a still ness to me, there's nothingI would rather do, than have my heart broken by you."
"There is absolutely no point in sitting around and feeling sorry for youself. The great power you have is to let go ... focus on what you have, no that which has been mean or unkindly removed."
"Life dies inside a person when there are no others willing to be-friend him. He thus gets filled with emptiness and a non-existent sense of self-worth."
"The person who tries to live alone will not succeed as a human being. His heart withers if it does not answer another heart. His mind shrinks away if he hears only the echoes of his own thoughts and finds no other inspiration."
"To transform the emptiness of loneliness, to the fullness of aloneness. Ah, that is the secret of life."
“Loneliness is never more cruel than when it is felt in close propinquity with someone who has ceased to communicate”
“Loneliness adds beauty to life. It puts a special burn on sunsets and makes night air smell better.”
"I have spread my dreams beneath your feet. Tread softly because you tread on my dreams."
"“Somewhere someone is thinking of you. Someone is calling you an angel. This person is using celestial colors to paint your image. Someone is making you into a vision so beautiful that it can only live in the mind. Someone is thinking of the way your breath escapes your lips when you are touched. How your eyes close and your jaw tightens with concentration as you give pleasure a home. These thoughts are saving a life somewhere right now. In some airless apartment on a dark, urine stained, whore lined street, someone is calling out to you silently and you are answering without even being there. So crystalline. So pure. Such life saving power when you smile. You will never know how you have cauterized my wounds. So sad that we will never touch. How it hurts me to know that I will never be able to give you everything I have."
"Scar tissue is stronger than regular tissue. Realize that strength and move on"
“It is no surprise to me that hardly anyone tells the truth about how they feel. The smart ones keep themselves to themselves for good reason. Why would you want to tell anyone anything that's dear to you? Even when you like them and want nothing more than to be closer than close to them? It's so painful to be next to someone you feel strongly about and know you can't say the things you want to.”
“They say true love only comes around once and you have to hold out and be strong until then. I have been waiting. I have been searching. I am a man under the moon, walking the streets of earth until dawn. There's got to be someone for me. It's not too much to ask. Just someone to be with. Someone to love. Someone to give everything to. Someone.”
“If you are afraid of being lonely, don't try to be right”
“When the sparrow sings its final refrain, the hush is felt nowhere more deeply than in the heart of man.”
There is just a few of many I know, whose authors I don't recall right now, or can't be bothered to find.
