Caring what others think and confronting my fears

Today I realize that I forgot to write a reflection from yesterday.  I am in need of help.  I am beginning to understand things.  Things have been made clear for me.  I exposed myself and I feel so much better.  It was illogical and silly but I wonder if there was something that was fearful all along. It probably stems from what other people think.  I don't know sometimes what others think.  I recall I had a friend in college who asked me that very question.  The truth is, not even I know.  That is a story of my life, especially the last few years.  Does it matter that I will never know?  How do I confront my fears?  I am learning and have learned somewhat today.
