Confused

What you create in me is madness.
I plundge deeper into my sadness.
You drag me down.
The answers can't be found.
I try to understand why you do the things you do,
I'm trapped under the ice I can't brake through.
I fall into the blackness again.
I thought you were my true friend.
My thoughts are gone, and dead.
My head is filled with dread.
You were here to help me.
But I just couldn't see,
You & I wern't meant to be...
