No I don't think your authentic self has anything to do with society or other peoples feelings its more of ones natural inclinations.

Example:

Homosexuality:
1. Mainly taboo in society
2. Mainly not accepted in Religion
3. Not the norm of society

Yet, I believe that my authentic self is gay.
I have been in relationships with men and even had sexual relations with men. I didn't hate it but I prefer those things with women. So regardless of society and my families feelings, I needed to follow my authentic sexuality to achieve my ultimate happiness.

As for the body/mind I think that when something your authentic self enjoys is ultimately hurting yourself...then that needs to be addressed and corrected. You will do this by doing things that feel unnatural, for the better of you.
