Who am i really?

My life has changed into something i didn't what it to be. not really a poem.

Who am I,
Am i me or someone else,
I can't even find out anymore,
I'm three different kinds of people,
Around my parents,
Around my friends,
And me alone,
Why does it have to be like this,
Can't I just be me all the time?
I sing very well,
But I am really good at acting,
That is my life,
A whole lie,
Can I find the strength to change that?
What can I do to be me?
