Escape
Shadows, shadows,
Hug me round
So that I shall not be found
By sorrow:
She pursues me
The repetition of these two lines highlights their importance.  The hug of these shadows is what ultimately protects the narrator, and this is her cry for help.  The repetition appears as more of a plea than the first two lines of the poem; perhaps there is more desperation in the lines at this point in the text. 
 The repeated use of “shadows” throughout the poem also presents an alliteration.  In addition, the “s” and “sh” sounds are by far the most common consonant sounds in the whole poem.  This gives it a very soothing, soft sound that can be related to the safe feeling of being in the shadows, but also relates to the quiet menacing of sorrow.
