Hey brave soul, your not fake when you are being yourself, you are only fake when you try being who you are not. You may be lacking self confidence at the moment, that doesn't mean you should try being like anybody else coz that won't build self confidence. Try not looking direct into they eyes of those you speaking to, look at least an angle away from their faces, don't think too much when talking, just talk. You will be loved and appreciated by those who find your worth.
i can't comfert you but i can tell you that you are not alone i do that do .. and i hate it to because I thought being fake will make them like me more but that's not true u know ... people love my real self more i came to realise that. but sometimes I still pretends to be someone else but i get in track after.. so don't worry about anything just be yourself and see
