Always been, always have

Let me just tell you
I'm not what I seem
behind this teenage life
I'm living in fantasy,
Yesterday I was a liar
Today I'm a beggar
Tomorrow I'm a friend
You really want to know her?
I once was a daughter
living in obedience
then I became a cheater
broken with no conscience
How can you love me?
Why do you believe?
Can't you see you'll get hurt?
When you'll only be deceived,
You brag I'm a saint
Do you know what your saying?
How can you trust me?
I've always been betraying!
I always have and always will
Always been and always here
Always sick and always hurt
Always, always, hurting dear!
