Sadness is often unpleasant, but it's an unavoidable part of life. It's natural to feel sad when faced with loss or disappointment. However, depression goes beyond sadness. People with depression often feel a deep sense of hopelessness. When you are depressed, it may feel like nothing will ever get better.
Depression treatment is very important because depression is a serious mental health condition. Contrary to what some people would have you believe, you can't just decide to be happy when you're struggling with depression.
