I used to taunt my fat sister. Now I am heavier than her with an eating problem.

I (28F) used to be very fat phobic for most of my life. Being skinny/average came to me without much trouble or food watching, and I was always very vocal about other people's diets and weights. In particular my older sister and mother have always been quite fat, so I made my fair share of snide comments to them. I really couldn't imagine why they couldn't just exercise a bit more or put down the bag of chips when they knew what it was doing to their figures. Then during covid, I started to put on real weight myself for the first time ever. During the lockdown I was forced to work from home and many of my social outings such as dancing and clubbing completely closed. I suddenly had to watch what I eat much more closely and in general began to eat more out of stress and boredom. Skip ahead to 2026 and I am over 300lbs. I'm heavier than both my sister and my mother and I am genuinely embarrased about it all. Only now am I realizing how hard it is to actually maintain your weight or lose any. I have an eating problem and am still putting on weight. It feels like it's I karma for my actions in the past, and it's eating at me, even after talking things over with my sister and mom.
