My brain has NEVER caught up. I have to see pictures (like, on a DAILY basis) to remind myself how far I've come. Otherwise, I just look in the mirror & there's that voice saying "good god woman! those thighs! that bra fat! and looka'dat belly!!!!"
So I keep several pictures of myself at different weights/ages, so I can LITERALLY see how far I've come (and how far I have to go) - it keeps it in perspective for me.
