Depression (mood)

Depression is a kind of feeling that makes you feel sad, down, or blue. It can make it hard for you to be happy and to do things that you usually enjoy. Depression can also make it hard for you to eat or sleep well, or to be around other people. It can make it hard to do things in school or at work. Everyone feels down or unhappy sometimes, but when it lasts a long time or gets in the way of your day-to-day life, it might be depression.
