Loser of Hearts

No one has ever lost their heart! It just doesn't happen.
Of course hearts get stolen sometimes, or they break and need to be fixed, but you don't lose your heart. The first thing we learn is to always take care of this most precious thing, to never take it off the silver chain that hangs around our neck. The first gift we ever get from our family.

Once a child is old enough to understand the importance of the task, it is handed its heart by the parent that had kept it safe before, and from this day forth wears it around its neck until the day of their marriage or their death. Well, at least in the best-case-scenario.
Anyway, here is where we get to the point of my first mistake: I had taken off my heart and carried it around in my pocket.

Something one should never do! But I didn't listen and I didn't care. It had ached too much for me to be able to bear it any longer. So I had unfastened the clasp of the silver chain and let my heart slide into my palm, feeling the immediate relief of the distance - the cushion it put between me and the pain. How could all those other people stand the agony of a cracked or broken heart?!
Of course there were ways to mend one: special facilities, experts, treatments... or if you were really lucky just another person's care.

But none of those possibilities appealed to me. I couldn't imagine giving my heart to some anonymous stranger in a lab who would artificially mend the cracks, or to go to another stranger who would tell me to 'go into myself, find the strength in my own power'... blablabla... none of that was for me. Just like I didn't think that there could exist a person in this world capable of healing me just by holding it. I never wanted to give my heart away again!
And then I went and lost it - and not even to someone! I lost it out of pure stupidity.
So now my pocket is as empty as my chain and I am terrified at the thought of what might happen if anyone found my heart. There exist an infinite number of ways to hurt me - the worst of them being the prospect of living the rest of my life without a heart.
I have heard of people giving away their hearts to someone and never getting them back. The stories never end well...
