Break-ups are the worst. All of a sudden the person who has been closest to you becomes almost a stranger and leaves your life. All the rituals developed together, all the plans you have been looking forward to suddenly become null and void. Scientists found that emotional pain has the exact same effect as physical pain. It comes from the same area of the brain.
But it isn't always pain and suffering. Eventually, everybody moves on and finds someone else. And all the lessons we have learned after a relationship and break-up are valuable.
If only we didn't have to re-learn them over and over again!
