Coping With Loneliness
Feeling lonely isn't in itself a mental health problem, but the two are strongly linked. Having a mental health problem increases your chance of feeling lonely, and feeling lonely can have a negative impact on your mental health.
Although most people need some kind of social contact to maintain good mental health, everyone has different social needs. You may be someone who is content with a few close friends, or you may need a large group of varied acquaintances to feel satisfied.
