I must be doing something wrong

Because I don't think you hear me whispering
I don't think you see me standing in front of you
I don't think you realize that you're on the wrong side of the window
Or maybe I am,
But I'm screaming for you
And you can't hear me
You keep on staring through me
And I'm slipping down the glass wall
So please break it down
And catch me before I fall
I never got to hold your hand
I still write your name on stick notes because I love the way it looks
I loved you before you left
And I don't know how to not
Because you made me
So
Freaking
Happy
So
Freaking
Happy
And I thought you were happy, too,
On the days that you weren't sad
We both had bad days but I thought we were happy together
Because when I talked to you, my mind was quiet
And I can handle the noise
But I need the quiet,
No one's ever made me feel like that
And you never told me how you could just walk away
I mean, I know life ***** sometimes
But it's easier to handle with you
All the times that you didn't get mad,
And I never forgot
The first time I cried after you left
I just told you that I hated that you were gone.
I sat up alone until midnight
Until I realized why I was crying
I count the minutes in my head and watch the paint peel off the wall
But I'll never understand
Why you left
