Confusion: Ethrel?

Drain me from
My dead life.
Stake my heart;
Embrace my strife.

I'm no longer here
To be with my love,
But to run with fallen angels
Descended from above.

If Ethrel is what you call me,
Then so it shall stay.
I'll try to not lt you down, Father
But offers infront of me lay.

Confused is how I feel.
And love is what I long for.
Trust is what you give me,
Though hate in me is stored.

Give me my collar.
Make your orders clear.
I'll do my best to follow
And train to lack in fear.
