Loneliness.

Loneliness is a complex and usually unpleasant emotional response to isolation or lack of companionship. Loneliness typically includes anxious feelings about a lack of connection or communication with other beings, both in the present and extending into the future. As such, loneliness can be felt even when surrounded by other people. The causes of loneliness are varied and include social, mental, emotional or even physical factors.

People can experience loneliness for many reasons and many life events may cause it, like the lack of friendship relations during childhood and adolescence, or the physical absence of meaningful people around a person. At the same time, loneliness may be a symptom of another social or psychological problem, such as chronic depression.

Many people experience loneliness for the first time when they are left alone as infants. It is also a very common, though normally temporary, consequence of a breakup, divorce, or loss of any important long-term relationship. In these cases, it may stem both from the loss of a specific person and from the withdrawal from social circles caused by the event or the associated sadness.

Loneliness as a human condition

The existentialist school of thought views loneliness as the essence of being human. Each human being comes into the world alone, travels through life as a separate person, and ultimately dies alone. Coping with this, accepting it, and learning how to direct our own lives with some degree of grace and satisfaction is the human condition

Loneliness is my least favorite thing about life. The thing that I'm most worried about is just being alone without anybody to care for or someone who will care for me. Loneliness and the feeling of being unwanted is the most terrible poverty. 
Loneliness adds beauty to life. It puts a special burn on sunsets and makes night air smell better. 
Love is something far more than desire for sexual intercourse; it is the principal means of escape from the loneliness which afflicts most men and women throughout the greater part of their lives.
Yet it is in this loneliness that the deepest activities begin. It is here that you discover act without motion, labor that is profound repose, vision in obscurity, and, beyond all desire, a fulfillment whose limits extend to infinity.

Loneliness is and always has been the central and inevitable experience of every man. Poverty is clearly one source of emotional suffering, but there are others, like loneliness. 
Loneliness is never more cruel than when it is felt in close propinquity with someone who has ceased to communicate. 
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. 

“The loneliest moment in someone’s life is when they are watching their whole world fall apart, and all they can do is stare blankly.” “Remember: the time you feel lonely is the time you most need to be by yourself. Life's cruelest irony.” “Two possibilities exist: either we are alone in the Universe or we are not. Both are equally terrifying.” 

“Nobody likes being alone that much. I don't go out of my way to make friends, that's all. It just leads to disappointment. ” “All I ever wanted was to reach out and touch another human being not just with my hands but with my heart.” 

“
Loneliness is the human condition. Cultivate it. The way it tunnels into you allows your soul room to grow. Never expect to outgrow loneliness. Never hope to find people who will understand you, someone to fill that space. An intelligent, sensitive person is the exception, the very great exception. If you expect to find people who will understand you, you will grow murderous with disappointment. The best you'll ever do is to understand yourself, know what it is that you want, and not let the cattle stand in your way.”
