Loneliness sometimes becomes someone's friend

Loneliness is an unhappy emotional and cognitive state caused by a desire for a close relationship but not achieving it. Individuals who do not want friends are not lonely people, but someone who wants a friend and does not have a lonely person. Loneliness is a subjective experience.
Loneliness is also described as social morbidity - a psychological mechanism to alert an individual to unwanted isolation and motivate him to seek social relationships.
As a social being, it seems that no one wants to be lonely, without a friend to share feelings or also have no emotional attachment with a partner.
