It depends on how much emotion one is giving away.
If you get punch by someone, it hurt at that time, but gradually heal back.
But once your soul of Heart get crush COMPLETLY, you can't fix it back!
It's always going to stay crushed. (On the previous incidence, some people had kill themselves because of a single rejection that damage his/her soul complete to a point that the person feels that there are no meaning to live...)
If your zodiac is a Scorpion, watch out on your love devotion ^_^ ( If fall in love with someone, most probably to give it ALL)
