T) You call me again

You call me again.
So often.
But always I refuse to come.
Now the wheel turns once more,
And new goals enter my sight.
But still you stalk behind me,
And when the angels fall and dissapear
You call me again.
I still have breath to fight you,
While my sanity hold you cannot harm me.
But with each lost moment,
As the past slips by untasted,
You gain a greater hold on my heart.
I fear soon
You will have enough strength
To crush it and take my life.
But the power is not yet come.
So, for now, begone!
I wait, until you call me again.
