What can i do?

Cant you see how much its affecting me?
Well, I suppose I'm hiding it pretty well
Cos I'm smiling on the outside
And acting like every things okay

But the easy signs you are missing
Like how I avoid talking about him,
When I say "Whatever" and "I don't care"
And the songs I listen to,
About losing someone who means so much to you

Well, now you should know the truth.
Because you really don't understand.

Whenever you say his name. I remember. I'm sad.
Whenever I fall into my own little world. He haunts every corner.
Everyday and Every night hes there, in my mind
And Whenever I'm alone. I Cry
Because I know I cant cope without him.
But what can I do?

Soaring around in my head
I feel like I was used
Just while the loneliness was there
And now I'm the one who's left alone
And soaking in the pouring rain of my tears.
What can i do?
