It makes you a mere mortal. But sharing it also upholds you in eyes of others. Sharing some of your most intimate and difficult things makes you open to sharing other feelings too, and receiving love and happiness in return.
If you fear darkness and you share your fear, you are very likely to be offered a candle in return.
When was the last time you shared your fear with someone? When was the last time someone shared your fears with you?
Don't be scared to share your fears.
