A rejection sometimes makes us wear masks and try to resist the desires of the heart. However hard we try, we sometimes go through situations that we consider to be rejection, and that makes us doubt our own abilities.
When someone feels rejected, the ego and self-esteem are most hurt. We want to be the center of attention, and when that doesn't happen, we tend to feel that those who reject us are not good enough.
In situations like this, the ego has a role to ensure that we are victims. In fact, when we don't get what we want, it's possible because there is something better for us out there.
The best way to overcome rejection is to accept the situation. Yes, that has happened. So, leave it! After all? The earth is still spinning and your life will not stop because of this refusal.
