Monsters Under My Bed

I'm too grown to believe in monsters under my bed or in my closet.  That doesn't mean things don't prevent me from falling asleep.  I wrote a blog I chose not to post for the moment.  A lot of feelings were written out that could be damaging.  Question: Is it better to tell the truth when it can be hurtful to others, but good for your soul or best to keep quiet and bury it in the backyard?  These are the things that keep me up at night.
