If I could say how I honestly feel....

Once I was so honest, but as I grew up, I stopped being honest. 
That happens to most of us.
Once I acted upon how I honestly felt, but now I can't.
I think about how others feel and think.
That's called growing up.

Before I never thought about becoming happy, but now I think about it.
I probably felt happy even before thinking about it. 
Is that mean that I forgot how to feel happy or just not simply happy?
I just don't know.
How does everyone know?

Is my heart gone?
Is my heart empty?
Is it possible that my heart can disappear?
What happened to me?
What happened to my heart?

I think I am empty.
