blue syndrome?

have you ever wonder why there are certain people who walks his or her life so painfully yet in front of people they dare to say this life is a wonderful thing and they purely agree. i wonder, not. its the same thing as what you always do in your daily routine, you go to school or work, talk almost about everything to your family or friends and even your partner, you have fun, you eat your favorites food, you give love and happily receive love but once your feet reach your room and the door is lock, you cry not but the tears just keep streaming out. There are no reasons for the tears to be invited. And you start to think why or what makes you cry but you don't get the answer. You don't even understand yourself. I know because it’s been years now yet I still don't have the answer...I am not crazy for sure, just stress. Yet does it powerful enough that even your mind cannot control your body or your body cannot control your mind? I wish there is an answer for that...and maybe some people out there also want to know what went wrong. This life is indeed an exciting place...i'm on my way of enjoying it and of course appreciating it. for me, no matter how hard your life is, no matter how many nights you have filled with silent tears to accompany you to bed, just keep walk on, straight and confidant yet with proud not but smile and carry with you love and faith in your heart while holding someone's hand. Hope you, who read this and understand, will end it with a smile.
