Help me before it's too late

The lights are on but my world so dark
My pain you'll never know
I smile for you because its easier
I'll never let it show
Dont try to figure me out
I'll never let you in
This is only for your sake
In my world you wouldnt know where to begin
You'd see the lies that keep me alive
The tears and pain I try so hard to hide
Dont come in unless you can make it go away
Wash away my pain I have to face every single day
Please help me before it's too late
Just look into my eyes and hold my hand
Maybe then you'll understand
Maybe then you could feel my pain
Just please help me before it's too late
