Tell me a secret she said

I unlocked my heart, searched my head—
What could I possibly hide beneath my blue-sheeted bed?

I eat my heart like bread,
Drink the tears I shed,
I never read anything new,
Only what I have already read.

Could that be the thread?
What I should not be doing instead?

I don’t understand my feelings;
I’ve always been misled.

Does that count as a secret?
I am blue—
Almost dead.
