Methinks it's natural to be "up" some days and down others. Consistent good cheer and grins tends to suggest (to me) that you're wouldn't be much of a thinker.

After all, you're facing a rather unpleasant situation. I suppose it would be nice if you just didn't give a hoot about how you looked, but you do - otherwise you wouldn't have changed your lifestyle - so there's bound to be some pre-visit stress. I can only tell you that you probably ought to spend as little time stressing over it as you possibly can. Read a good book (that always takes me away), soak in a hot, bubbly tub, listen to some soothing music...whatever mellows you out.
As for WHAT you lost - water, fat, muscle, your last few bags of potato chips and last few slices of pizza - what do you care WHAT it is, so long as you're not carrying it around anymore? It's GONE! YAY!
AND, don't worry about what they notice or don't notice. It's YOUR body, girl!!! YOU'RE the one who has to be comfortable with it, not them! You should be *changing your lifestyle* because YOU haven't been happy with your weight - not because they weren't. Let them wory about their OWN bodies. Yours belongs to you!
But they're not evil people, really, and I'm sure their concern stems from how much they care about you. But, in this instance, YOU are the one who has to make choices for yourself, and they can't do an awful lot about it, except air their feelings. I agree that "thanks for your input" would suffice....or how about this? Thank you for caring so much. I love you, too. I'm working on it. I've lost ten pounds, although it might not be noticeable just yet". That's called open communication. It works!
The other thing you might think about doing is calling your sister and talking candidly with her about your feelings. Tell her that you've changed your eating habits, you've lost ten pounds, and plan to lose more, but you're feeling really uncomfortable about the visit, because you feel like the others will be judgmental. That way, you'll have a supportive ally, and won't have to face the crowd on your own at all!
Have a good day! Congrats on the 10 pounds!!!!
