Moody day

Have you ever thought before what would you be in the future? Have ever thought of what have you done in the pass few years?
I'm wondering today! Thousand of uncertainties came across my head since saturday night when i was being alone at room surfing...until the next day i woke up i listen to the song tht someone gave me...make me more emo-ing...If a day of my life without smile and happiness what would the day become? I question myself what is the life really mean? This question sound like mundane but in the teaching of Buddhism i learn before and i have totally lost of it now...losing the light in front the travel of darkness is the scary thing. I should back to the temple for renovating myself and back to the actual mean of life...
