Lonliness

"If you are lonely when you're alone, you are in bad company."

John Paul Sartre


Loneliness is not what it seems. One does not feel lonely because one is alone, but because of a feeling of lack - a feeling that something is missing.
Loneliness is essentially independent of how many other humans are around.
It has much more to do with one's self-esteem - one's sense of inherent worth and self-confidence.
