Depressed means feeling very low in spirits for a long stretch. Feel depressed, clinically depressed, a depressed mood.
In ordinary speech it means sad, and in medicine it means something more: a lasting low mood with loss of interest, changed sleep and appetite, and it is treatable. Anybody feeling this way for weeks is worth a doctor's time. The word also means pressed down.
