Wow i can totally relate to this. I just went thru this and it caught me off guard i must say. I really wanted FFS and I am happy that i did now that I am starting to work thru recovery and being presentable again.
You know you would think that changing ones name, gender presentation with clothes ,hair and HRT that this would have been the big shot to family and everybody else. Well it was not for me and my family and
friends.Post FFS shocked most people that knew me to the core and it unsettled them. They lost the familiarity aspect and my mom was quite upset as she said there was no resemblance anymore. Others were quite taken a back and had to readjust all over. As I have progressed 3 months post now my mom made the comment that she can still see the same person thru my eyes and this helped but what really made a difference for the comfort factor was that I was literally confused for my sister a few times and others thought I looked allot like her. The made my mom feel a lot better. There is a very strong female family resemblance now which is good and desired for sure.
For myself it has taken a while to adjust and become comfortable. It is getting harder to remember the old person and the new one is almost normal now

It is a big change for some of us and the mental and emotional side of FFS does not get enough attention in my opinion as it can be a whole new journey of acceptance as the face is such a critical biological component to our humanity that goes back to caveman days.
