I hear what you are saying, I had a few scales where I became obsessed with weighing myself. I am debating getting a scale again but I don't want to weigh myself on it too often and then get frustrated. I have had an unhealthy relationship with the scale for awhile, sometimes at doctor's offices I have asked for me to not know my weight, closing my eyes or stepping on backwards. This is something that I definitely struggle with.
Take care, good luck.
