What should people watch out for in spouses/friends that are unemployed?

Changes in behavior. Many unemployed people do not get any psychological nor behavioral problems due to losing jobs. However, one may get anxiety symptoms due to worrying about how to pay his bills for food, housing, gas, etc... One may get depression symptoms due to feeling hopeless, unappreciated, worthless, etc... Family interactions may worsen if there were already problems at home. Substance abuse may increase.
