It sucks when you realize you have spent most of your living life trying to pretend you are normal at school, church or work. Trying to pretend your family is completely normal, trying to hide the craziness in your head, trying to cover up your awkward PTSD symptoms, trying to be as good of a person you can, trying to maintain the peace in any situation, trying to be as spiritually strong as you can for your faith, trying to be as responsible as you can and work as hard as you can and be as honest as you can.
Because underneath everything, you are scared of yourself being crazy, dysfunctional, stupid and messed up. All because of growing up on a very abnormal family where you were always the scapegoat and always yelled at no matter what and then bullied by kids at school and most of your peers at church talked about you to others because you came from the weird messed up family. So you were pretty much isolated most of your life growing up and thus trying to fit in and appear normal to everyone around you. Of course growing up in a strict religion, that is considered a cult and separates itself from the rest of the world, didn't help either.
