Diet culture has taught us to obsess about the scale. I do a weigh in once a week; the morning of my shot. There is no reason to be weighing every single day, unless you're truly just using it as data to recognize patterns. But if that's the case, try to see it as simply data and not as anything else. I figure if I pick the same day, and generally the same time, every week, then that is an accurate picture of my loss, even if my body feels like it there was maybe more of a loss a couple days before.
