Some people get their self-worth from whether or not they are loved.
Some people are more energetic, cheerful, and productive when they are sharing a love relationship.  There is someone to share your good times and to comfort you when things get rough. 
Some people become depressed, lethargic, and melancholy when there is no love in their lives.  The feeling that no one loves or cares can trigger suicide in some people.
