I didn't see the original, but to follow Mrs Izzy's lead, none of my fears or worries came true, in fact a number of good surprises was in store. Friends came out of the woodwork to support and encourage me. (I had no one prior to transitioning).
I never wore breast forms in public, and the question of "where's your breasts?" never came up. (But when The Girls did start showing up..."OMG Beth! You've got breasts!" was heard about once a week. All were meant as compliments)
+1 on "my happiness, not theirs." We're not here to put on a show for others, and if they don't like it...not our problem.
I started at 47, now 50, and life is good.
