I do the same thing you do. Bump into doorways, don't leave enough room to sit down, etc. In general, I guess I feel like I really can't be that big! Two things make me realize that, yes, I am fat:
-trying on clothes
-looking at pictures of myself

Otherwise, I blissfully go along (in denial) thinking I'm, oh, maybe 30-40 lbs less than I really am. Thanks to LCing, though, it won't be my imagination for much longer!
