A found poem

I think this poem, in some sort explains my feelings at the moment, except the "I'm better off dead" part, it's a feeling more than a physical act to harm myself.

You tell me that you care
You tell me that you've changed
but when I let you back in my life
You prove me wrong.
I should never have trusted you
I should never have said
I miss you baby,
But I'm better off dead.
You said that you care
You said that you'd be here
But whenever I need you,
You were never there
How am I supposed to react
To you coming back?
You leave me breathless
With nothing left to live for
What am I supposed to say
When you tell me you've changed
But reality strikes back
When you walk away
