When your heart was broken my someone you're madly in love with but you don't feel the pain until well after the date-of-break. You usually feel ok and undepressed for anytime from a day to a week; usually because you try to put on a macho, "I don't need you" facad. Then after the set time your emotions get the best of you and you start to expirence the natural symptoms of heartbreak. Sometimes they could get worse than usual.
