One of the replies from way back when this post first started hit on a good point. Why would FFS that dramatically changes the face be any different than losing 100lbs, in which you look totally different not just in the face but everywhere else as well? In my opinion, for myself, I've never really liked how I looked anyways, so why would I want to keep that just so that I can "still be me?" In my eyes, it's my mind, my personality...it's me...that makes me who I am, and not how I look. The changes I make to my outer appearance are merely to more easily blend in as who I am and be accepted as so.
How I see it, you're never going to look the same your whole life anyways, so what's a dramatic change now going to hurt? As you age, how you look changes drastically over the years. People who see you more often don't notice it as much, while people who don't see you as much notice it more. After the FFS people will soon become accustomed to it and they'll forget what you looked like before, while still knowing you. Others who you don't see often probably wouldn't recognize the old you either anyways.
That's my take on it for me personally, and since everyone is different and has their own opinions on what suits them then there's always a different road for someone else. Me...I'll be happy after January rolls around and I can feel more confident that I look like me, while continuing to be comfortable in the knowledge that I still am me no matter what I look like.
