I dont' know how everyone else experiences things, but for me, the term "heartbreak" didn't make any sense to me until I experienced it. It actually hurt in my chest,.and then there was a void, like my chest caving in. It doesn't make sense, when you "know" that emotions are all in your head, but it happened, anyway, despite all logic. But, when I found the guy who ended up being my husband, everything started making sense again, and I got the courage to explore and do new things with my life that I couldn't have before. I don't know why all this happens, but I know it does.
