I'm going to leave a bathroom scale at my significant other's house
That feels very odd for you to do, why would you leave a scale in their house?
The scale is being really annoying after it labeled me an obese person.
You shouldn't see it as an insult and see it as a means to get better and monitor your weight to improve your health. Your body and your significant other will thank you in the long run.
I hate to be called obese, I'm really deformed.
Well, if you think you do not like how your body looks, then I think it is best for you to do something about it instead of thinking the the scale is insulting you. I wish you luck and I hope you lose some weight in the process!
