A Quote by Leo F. Buscaglia on needs, anxiety, and contentment

But man has other needs as well: emotional needs. These, too, are few, but every bit as important as his physical requirements, yet not so simple. If they aren't met, they can be as devastating as physical hunger, as uncomfortable as a lack of shelter, as incapacitating as thirst. The frustration, isolation and anxiety brought about by unmet emotional needs can, like physical privation, produce death or a degree of living death - neurosis and psychosis.
