Probably means that it takes time to get over something. As an example: If you're mad at someone now, eventually, that grudge will dissipate in who knows how long. Or if you broken up recently with someone, it's hard at first. After a few days, weeks, or months (depending on how long you were in a relationship for and how serious you were), you'll eventually get over it and move on. Takes time to get over things so in a sense, heals your emotions and you're back to your regular self doing regular things without thinking about that person on a constant basis.
