Running scared

I'm trying to break free
But you just won't let go
You're ruining my life
I'm about to blow

I want to be my own person
But you're controlling me
You say you love me so
Yet you just won't set me free

So I'm leaving you now
I'll make it on my own
I'm strong enough to do this
So don't expect me home

You used to be so different
You were kind and always cared
But now you're a controlling bully
And yes, I'm running scared.
