I Don't Get It...

It's not really a joke but just a statement. A heartbreak is something that is extremely hard to go through. It literally feels as if your heart is breaking in two. The picture means that in some cases people think that dying would be easier then living through the torment of a heartbreak. Of course giving up your life should never be the decision but the thought does cross some people's minds. Hoped this helped you understand!

I understand. After all, I made the picture. =\

Oh sorry, I thought with the title and all it meant you found the picture and didn't understand it. My apologies I misunderstood.

It's all right. Don't worry about it.
