Sounds to me like you have a guilty conscience. You're trying to run away from God and the people at the church - but then you let them be your facebook friends and that means they can see whatever you post. I have a nephew who is 26 and he's one of my facebook friends, but he's hidden because I don't want to read about his drunken escapades or read the profanity-laced comments of him and his friends.
Facebook is a public forum - so don't put anything on there that you don't want ALL of your "friends" to see. And maybe that woman didn't use the right tone - but I think she cares about you and is disappointed in your life choices.
One last thing - you can't run away from God.
