People are Social Creatures

Humans are by nature social animals, even the most solitary individual may enjoy being alone but will never enjoy feeling alone. Whether you are the kind of person who has a lot of casual friends or only a few close friends, feeling like you are part of a group that supports and cares about you is an important part of mental/emotional health. Cherish and nurture healthy relationships with friends, social groups, and family... But never be afraid to leave the unhealthy ones.
