I Want my heart back

I can't sleep
I can't think...
I haven't eaten in 2 days

You were my everything
I was happy because of you
There were days when nothing could bring me down

There's a piece of my heart
That i have yet to find
Its only been missing since you left

Why did i believe you?
Why did i trust you??
Why was i so stupid to love you...

i want everything i ever gave you back
I want my life back...
But most of all...I want my heart back
