Some part missing

I am here to claim back part of my heart, that I have accidentally left last week.
Slowly, I walk into the little cozy forest, finding my heart. I found it almost at once when I walked in. I dig a hole, and take out the part that I left a week ago, then place another part that I thought it suppose to be here back in the hole.

I walk out the forest, with a lighter heart, beating on a more energetic pace.
I stand before the blue sea near the forest, enjoying the sea breeze. I opened my arm, and let the wind filled my T-shirt, the wind around me bring a little coldness, I thought this is some new fresh feeling, ignoring the little emptiness that is spreading bit by bit.

I close my eyes and feel some breeze stroke on my face gently, then dance with my hair. I am smiling, a not too sweet smile. I thought, this is a norm after changing that part of my heart.

I took a deep deep breath, too deep that I nearly choked.
Coughing a little while I swallow some cold air in my body, I shiver a bit due to the unexpected coldness, then I feel something is spreading in my body. My heart began to weight more.

I took a deep breath again and I start to notice some difference. The cold air that flow in to my body through my nose, pass through the wind pipe, and then my lung, finally dissolve in my blood, and travels to every inch of my body.

Something is wrong. Therefore I went back to the jungle again, trying to find my part of heart that I left a while ago. But, I couldn't find it anymore. I have no choice and left with some part of my heart missing. I have always thought that I would have a lighter heart when I buried some part of my heart, strangely, my heart is heavier then ever after missing a part, not knowing, the missing part of my heart has filled with something cold, something cold that called missed.
