My wishes never come true

Is there meant to be happiness in this world
I wish there was some in my life but obviously my wish will never come true
I dream of being happy, but it never happens
If only someone could explain the meaning of life to me cause i can't seem to find out
they say tell me when our sad, but im the kinda girl that keeps to herself
On the outside i'm happy and bubbly
On the inside it's the total opposite
I want to be someone different
i really do!
