Depression: Diagnosis is key

By Mayo Clinic Staff

It's perfectly normal to occasionally feel sad or upset, or to be unhappy with situations in your life. But with depression, these feelings linger for weeks, months or even years. If you think you may be depressed, seek medical help as soon as possible. Depression usually doesn't get better on its own, but depression is treatable. Remember, help is available.
