When did I become her?

Where is the old me?
The one that could actually love,
And care for someone.

Where did she go?
When did she become so heartless,
And uncaring?

Where did that heart go?
The one that was broken,
But still knew how to love?

When did it repair it’s self,
And turn black?
When did it close it’s self off?

When did my mask,
Become the real me,
And where did the old me go?

How could I become someone,
Without evening knowing it?
