I have to say this is a beautiful poem very pleasent and sweet.. It really is lovely..

I love poems that use darling in it,

A fragile heart I do possess,
That cringes at the brink of day.
I love this, I love how you describe how ur heart cringes. This is such a beautiful, love entwined poem.
It has an enviable amount of emotion, this is truely flawless

Keep writing ^^
