Struggling with Eating Habits and a Mother's Triggering Behavior

I've been struggling with eating again, whether it is restricting or binging, depends on the environment and my emotions. my mother was always the spark of it, and recently, she has decided to purchase/move an already purchased scale to keep in the family restroom. my issue isn't with her owning one, but she puts things like this in places where it's out in the open despite me asking her to put it somewhere where I'm unable to see it. I used to weigh myself on a daily basis, sometimes 2-3 times per day, at the peak of my habits. I'm terrified that I'm falling down the spiral again. I can't look in the mirror without thinking about it and I weighed myself for the first time in a few years the other day, and I haven't been able to try on clothes in a week without sobbing uncontrollably. I'm on a trip currently, so my access to the scale is cut off. but I need to figure out how I can confront her without seeming selfish before I go home.
