Hi Happiness, would you stay?

Hi sugar, I have a lot of things in my head. I can't explain what is it. So many pain in this past two years, actually some of them sweet too.. I mean bitter sweet. 
Well, with my family around I always feel happy, but I need something more.. 
I don't know why is my heart always seems empty.
I'm afraid to get hurt, I'm scare. 
But I won't cry out like a weakling any longer.. and I won't shed any more tears. Smile and let your tears passing by.
