Interjection: Who are you fooling by wanting to expose more if someone comes and gives you Mussar of any sort( For Tznius issues)? You may have struggles within your self ,but you are hurting no one more than yourself! I think you really NEED TO LOOK DEEP WITHIN YOURSELF TO SEE WHY YOU WOULD REACT THAT WAY.
You should try to get your self the proper guidance to see what exactly intimidates you so.
