I know there are a lot of similar blog posts floating around the world wide web, and by no means am I trying to “copy” anyone, I just wanted to add my two cents to the topic.
First, and probably the most important, depression is not the same as sadness. This is a common misconception that I have personal experience with. Sometimes sadness can feel so debilitating that you may think you are depressed; very understandable. With that said, sadness is a completely normal human emotion, that we all experience within our lives. It usually occurs when you have experienced a disappointing event, a hurtful situation, or when grieving over a loss. However, once you overcome said event, or situation that brought on this emotion, the sadness dissipates.
