You everything, me something

You held my hand when I was falling You walked beside me when I was lost You gave me light when I lived in shadows You gave me hope when I was empty I gave you my heart, and you held it gently I gave you my trust, and you carried it carefully I gave you my soul, and you guarded it fiercely I gave you my love, and you promised eternity But promises are made of fragile threads And eternity broke in a single moment Your hands let go, and I fell farther Your light dimmed, and I lost my way Your love was the anchor that pulled me under You saved me, only to leave me drowning You built me up, only to tear me apart You loved me, only to destroy me completely
