<h3>What is depressive disorder?</h3>
Depressive disorder is a mood disorder characterized by persistent sorrow and loss of interest. Clinical depression, often referred to as major depressive disorder, has an impact on your emotions, thoughts, and behavior and can result in a variety of mental and physical problems. You could periodically feel like life isn't worth living and find it difficult to go about your everyday chores.
You can't suddenly "snap out" of depression; it's more complicated than a bout of the blues. Depression could require long-term therapy. However, don't give up. The majority of depressed people experience less severe symptoms thanks to medication, counseling, or both.
