This is so true. I'd even go so far as to say that once you've come to terms with the feelings yourself, coming out to others is nothing as tough.] I don't really see that it's much more embarrassing than coming out in the first place.
I think that with the experiences we have (the abuse you mentioned being one such experience), we very quickly learn to stop caring what others think. In fact coming out requires that in a sense. So looking stupid shouldn't be an issue, because you can bet that to some we already do!
The only thing that really matters is whether you are being true to yourself. Looking stupid shouldn't be part of it. Just as you shouldn't transition for anyone but yourself, you shouldn't de-transition for anyone else either.
