Can't Do A Thing (With My Heart)

Ok I can't understand some of this so if it's wrong please correct me...the blank line I don't know. If you know them email me.

I paint my nails
I curl my hair
There's no excuse
Why I should care
This is where life without you starts
I'm picture perfect from the outside
But I can't do a thing
Can't do a thing
With My Heart

I'm trying out
This new perfume
My counselor should be here soon
I'm praying I don't fall apart

But I can't do a thing
Can't do a thing with my heart

And now your gone
But life goes on
I will survive come one day
It may take time
To get emotions in line
I'll get my heart to behave

I'm walking out
In brand new shoes
I'm taking steps
To get over you
And I've already come so far
If I can't change the way they are
Cuz I can't do a thing no
Can't do a thing with my heart
