Everything I Do...

 You yell
I have so many stories to tell

I'm guessing you're bipolar
It worstened as you got older
When I ask what's wrong
You cry like a sad song

I'll never understand why you hate me
I only tried to protect you
I never want to forget you
Yet,
I always mess it up

From sister to brother
From one to another
I'm nothing but
A screw up
