I seem to be collecting hearts...

Some gained unintentionally,
But I worked hard for most,
A few are a bit warn now,
And I broke some too,

If I have yours and you'd like it back,
Just let me know, although,
There's no guarantee, as,
It may be yours that I'm currently using,

I don't mean to keep it from you,
But my heart was taken long ago,
I'm just trying to find one that fits,
So I can be happy again soon.
