It is so important to be your authentic self, ALWAYS. You will only hide your true nature and character if you are not happy with who you are. How can you then expect someone ELSE to like who you are, and why should they even try? Must be aweful to have lied about who you really are and then have to deal with wondering whether the person will still like you when they discover the real you. You cannot hide behind a facade or lie forever, eventually it's all going to collapse and then you must be prepared to accept that you will probably be rejected, and deservedly so.
