Don't you think heartbreaks are extremely understated? In fact the whole idea of heartbreak doesn't make sense to me. Hearts don't break; breaking is a very lousy word to explain what your heart feels when it experiences loss. Breaking happens in a nanosecond, what happens to your heart is a far more elaborate. That kind of emptiness you feel like something within you died, heartbreak as a word doesn't do justice to it. It comes closer to drowning, that struggle between not completely living or dying. Also, broken things can never completely be mended. A mended heart isn't capable of experiencing a feeling as strong as love again; it would rip it apart in a second. And again, you never love the next person the same way as you loved the previous one. There isn't the slightest of resemblance in the way the two made you feel, it is entirely different. So your heart doesn't break after all, it drowns; and the waves leave it at the shore. Then someone picks it up, and breathes life into it again.
So don't worry, if your heart feels like it's drowning, you're probably going to reach the shore very soon. :)
