Depression is a common and serious medical illness that negatively affects how you feel, the way you think and how you act.
Signs and symptoms of depression can include:
delayed psychomotor skills, for example, slowed movement and speech
fatigue or loss of energy
feelings of worthlessness or guilt
impaired ability to think, concentrate, or make decisions
insomnia or hypersomnia
recurrent thoughts of death or suicide, or attempt at suicide

Depression is treatable. Three components to the management of depression are:
Support, ranging from discussing practical solutions and contributing stresses, to educating family members.
Psychotherapy, also known as talking therapies, such as cognitive behavioral therapy (CBT).
Drug treatment, specifically antidepressants.
