I think it is so hard to destroy the scale because even in recovery, it is one last little piece of control. So that if things “get out of hand" with our weight, we will at least know. Because the only thing scarier than gaining (more) weight is not knowing when we gain weight.
The number on the scale has the ability to determine my mood for the entire day or even week and had became what I used to measure my worth..
No matter what the number was - high, low, or even if it remained the same - it was never, ever good enough. Logically it would make sense for a person who finds it so difficult to see the number on the scale to simply throw it out. Never weigh themselves again. That's not how it works.
For some of us the scale becomes the last piece of control we can grasp onto.
Letting go of the scale can be one of the more difficult parts of recovery for some, but please believe me when I say it is worth it. Although there might be a period of "withdrawal" and temptation to seek out a scale, it does not mean those eating disordered thoughts need to win. The best advice I received was to get angry and smash my scale with a sledgehammer, run it over with my car, or at least have a friend hide it. With a little time, it is possible to be completely free from compulsive weighing behaviors.
I've said it before, but I will say it again - life is too short to allow a bathroom scale to control my life. If you haven't already, go throw out your scale... now.
