Why would someone pierce their heart?

Question

I'm writing a poem, and I need reasons for piercing one's heart.

Not like, medical reasons or because you're mentally ill or something.

like, figuratively.

Answer 1

Someone that's always disappointed or that's always disappointing someone else, or someone that's always been let down or someone that's always letting  someone Else down.

Answer 2

It could be because of jealousy of love being depressed by someone or something. Proably i think for being a depressed by someone who hurt you that you loved. It's kind of like love but with more of that sorrow to eat i hope you do good :D

Answer 3

Theres always the easy way out: love

Or, it could be because they just don't want to feel anymore; as in, their emotions are destroying them and they just want to be free of them. Hey, actually, that doesn't sound like a bad idea....

Answer 4

i would have to agree with heartshapedbo,.that does sound like a fitting answer

Answer 5

Moving too quickly or slowly... depending on what type of emotions you might be describing.

Answer 6

Needle and thread?

Then  

This heart is but a patch, pierced through

Yet adorning the chest that holds thoughts of you

Answer 7

Only a soulless buffoon would ask such a question.
