What is the definition of depression?


Depression is more than having a bad day or feeling sad now and then. It’s not a feeling that passes quickly or that you can snap out of easily. It’s a serious emotional health condition where individuals feel persistent sadness, and that sadness — along with other symptoms — interferes with school, work and daily life.

Depression is different for each person. One person might be too sad to even get out of bed; another person might express his/her depression through anger or restlessness. If you’re not sure if you — or a friend — is struggling with depression, consider the symptoms listed below. Depression can be effectively treated so don’t hesitate to reach out for help.
