Depression: The Mental State

Depression is inside everyone. Some are opened to it early in life; while others are drawn to it by tragic events. Deep down inside I wonder what it was for me. For years, I felt alone. Can you say rough childhood? My only escape was to escape, if you know what I mean. Now it's become some form of desperation on  my mental emotions and the things I choose to hold inside whether it be anger, stress, sadness, or relationships only tend to build and cause major complication to the situation. Yet, no one understands. Many say they do, and in reality we know they don't. Some try to understand us, and mostly for their own reasons. Why are people this way? Why is it that those like us shutdown? Why do we hide behind the world fearing that we'll be judged if we open ourselves up. Yes, some of us are shy but we all know how deceitful it is to judge a book by it's cover. How do we overcome this? How do we manage picking up the pieces and fixing our reflections in the mirror? Do we find groups of people like ourselves to pour our feelings into? Do we write them in a book hoping no one will ever see how we really feel as opposed to the character/front we put on around others? Why must we struggle from depression? Why can't we all be that brave bold person we known deep inside that we truly are?
