I had a lot of trouble accepting BMI as anything relevant.
I take care of many large women as a midwife, and I am a little blind to weight. I like them as people first, and weight and BMI are just numbers, and people are never just numbers to me as a care provider.
I also resented the BMI because I was classed as obese, and I didn't think I was obese. BUT, a big part of my weight loss journey was accepting that I was obese, I am fat. (hence the name fatmad) Once I accepted that I was fat, I could start thinking about losing weight.
I am now classed as overweight

so I am please about that. I plan to get under that at least. Ironically, I was underweight for many years. I was quite skinny when younger, and didn't learn to eat properly as a result. As a care provider, I knew what to do right, but didn't, since I was in denial.
Now I am eating better, and I hope getting fitter, (still find exercise a challenge, I do NOT like it or enjoy it much at all).
I think you can use this label, and accept it, as part of working toward your better health. Good luck!
