What happened...?

Remember before?
We used to be BEST friends.

What happened?

Before I met you, I used to be friendly.
But then I met you, and I turned out to be a *beep*!
Friends noticed, mum noticed
I used to be healthy and polite.
I am lying in my bed at night.
Can not sleep, what the *beep* is right?
Am I mad?
No YOU are!
You betrayed me.
When I first started to really know you,
I can see the true.
You meet one, and start a new friendship.
Then they see the truth, and you give them a kick!
The truth is that you are a *beep* up liar!
You know, I DO NOT LIKE YOU *beep*!
