Thanks everyone for your suggestions and support during what was clearly a low moment for me last week. I don't know how I got so focused on the scale--I guess because I still don't see the results I want in the mirror and I wanted to have an end in case I never do (and now that I have an end, I want to get there). It's also a very tangible, immediate way to judge results. Measurements and body fat percentages don't change from day to day; weight does (even if it's just water).
I am definitely not too skinny. I still carry a lot of fat in my hips and stomach and I really just barely have the beginning of muscle definition. When I flex, you can see some muscles, but when I'm relaxed, I still look pretty soft (you can't count my ribs--that's for sure!). At this point, I've given up on the perfectly flat stomach but I would really like to see the roll of fat I have there reduced a bit more. If I can get that to happen without getting down to 115, then I'll give up on 115 as a goal.
The good news is that when we took my measurements today everything except my arms was down from where it was last time and my body fat percentage has dropped as well, by about 2.5%. I'm at 27% body fat, so I think I still have a little ways to go, but I am making progress.
So I will keep plugging away.

I am having trouble with the idea of eating more just because this calorie level worked so well for so long. But it would be nice to have some extra calories to work with. It also occurred to me that this fear is sort of silly; if it doesn't work I can always go back to 1300. So I think maybe I will try more calories for a couple of weeks and see what happens. I'm going to stick with weighing myself every day, though. I understand what everyone says about not weighing every day, but for me, knowing is better than not knowing.
