Usually people judge their own actions differently than others. Whether it's because of their own emotional motives or because they're simply trying to feel better about themselves, they sometimes end up judging themselves more harshly than others.
This can lead to a double standard. It can also lead to people who operate below par in their work, and this can be very serious. In addition to the negative consequences of operating below par in their job, they may also end up spreading illness to others.
In some cases, it's better to speak your truth and let others know exactly what's going on in your life. This can be done through a written letter, or you can even make a phone call to someone who you trust. This doesn't mean that you need to hide your feelings in order to get their approval, but it does mean that you can be your true self.
