A first love is electrifying. It rushes through your veins like fire. It causes your heart to feel like it's on the brink of explosion at any time. It makes you crazy. You have no idea how to contain that craziness. You don't know how to function without it. You don't know how to function with it. There is either an incredible ending to the story, or a heartbreaking one.
Perhaps you think I'm crazy for suggesting anyone let themselves fall into this pit of despair, that I'm an emotional sadist of the worst variety. But darling reader, I assure you I'm not, because eventually something happens to every single person who loves someone who doesn't love them back: they manage to stop being in love.
Too often we focus so much on a door that has closed abruptly and unexpectedly in our faces that we don't realize that the world is full of other doors that are open to us. You won't find your happiness demanding that a certain closed and locked door reopen; all you will do is miss seeing alternate avenues of opportunities that are available to you.
