Depression, though not explicitly mentioned by name, appears in The Sims and its expansions. It is the result of a Sim's motives not being fulfilled. It is inspired by the real life mental disease which shares the same name. If a Sim's motives are neglected for long enough, especially social, the Sim's mood will begin to drop into the red area, and the Sim will eventually become depressed. A depressed Sim will refuse to look for jobs, whether it be via computer or newspaper. If a Sim is already employed, he/she will not automatically decide to go to work when the carpool shows up, instead they will have to be prompted. He/She will also refuse to take part in most skill-building activities, such as chess or reading a skill book. In The Sims 2 and The Sims 3, nightmares can also be a result of depression. A depressed Sim will occasionally weep and have bad thoughts. An easy, though expensive, way to fix it is to send them on vacation.[TS3:WA] If they become depressed on their vacation, it will be needed to send them home. Having little funds can also set a Sim's mood plummeting.
