pro tip for people who don't like being told what to do
speaking as someone who doesn't like being told what to do, the best way to stop people telling you what to do is to just do the thing before they get to tell you to do it.
this is exactly like my years of growing up being told to "eat more" and "eat faster" and "eat more frequently" because i was too thin and skinny and underweight and it was bad for me. and i know they're right and were always right, but something in my young, restless mind just didn't enjoy being told what and when and how to eat, so i spent years eating in spite.
i didn't enjoy eating whenever we ate and i never got seconds of anything. eating felt like a chore because i knew it was immediately open season for everyone at the table to comment on how i was eating wrong or too slow or too little and it just made eating so unenjoyable.
my mom tried so many different kinds of vitamins to get me to fatten up or, at the very least, achieve a "normal" weight for my age and my height, but none worked.
a year ago, at 29-verging-on-30, years after the vitamins stopped, i just decided to see what would happen if i just... ate. i figured, it might stop people from commenting and nagging. so i ate like i'd never eaten before. i ate a lot, and more frequently, and i tried not to go too slow.
in two months, i was closer to my "weight goal" than i'd ever been in my life. the goal was to reach an agreeable enough weight that i could donate blood if i ever went to a blood drive (i'd never qualified for those because i was always considered too underweight).
nowadays, my weight has kind of plateaued. i'm still a couple kilograms away from the "weight goal", but i'm no longer too skinny or thin or underweight, and now people compliment me for eating "better". i guess they're still comments, but at least they're not dictating how and when i should eat.
anyway, the moral of the story is that if you're sick of people telling you what to do you should just do it or beat them to it. like the dishes or the laundry. or eating or becoming better.
i was admittedly a few decades too late to my thing, but at least i did it. i feel the healthiest i've ever been and i'm also supplementing my new way of eating with a workout every other day (at home because i can't be bothered with a gym subscription right now).
