text: Be yourself.  This is a very difficult question to answer.  Some are able to answer it quickly (I know some who realized it when they were about 10) and some are able to answer it very late (I know one guy who was not able to answer that question until his 40s).  This takes alot of insterspection.  There are also the "societal norms."  But don't be afraid of yourself.  Perhaps you will realize this was a "momentary" feeling, or you will realize that this is how you've "really" been feeling.  Either way, you will become a greater person.
