sometimes, in the middle of happy time, there's still sadness...

I put all the exciting posts on facebook, and hide all the sadness here on DS. At least, I still have one place to turn to. Yes, I'm grateful.
Lord, I'm doing all I can... just like a Robbie Williams' song. I never feel bored, only happy, or sad. I never say no whenever a friend ask me out, girls' night, parties, drinks after work... I have several friends. I'm happy. But I still have sad moments among that happiness: a few minutes in the night before going to bed; a Sunday morning; having dinner alone... It's not 'bored'. It's sad.
When I left my ex, I guesse he was the weak person who couldn't figure out what he really want in life, couldn't bare the solitude so that he turned to that girl. While for me, I could find the strength to walk away from him, though I was the one who was hurt, but I still bared it, and walked away.
Yes... Now they're just some moments of loneliness, sadness. When it's ok, when I see my friends this evening, I'll be cheered up again.
