Hey Nona,I'm so sorry for late reply, I've been busy with uni
So, my obsession with weight has been there as long as I have been aware of my own existence. My very first memory consists of a family meeting where they were sharing diet tips and me running to my parents' room to weigh myself.
I remember gaining weight at the age of 3 and being teased for it a lot by other kids in the park and daycare. I have a particularly traumatizing memory from daycare. Sons of daycare attendants, who were much older than we were at the time (they were around 15 ) would hang out there and pick on literal 3 year olds. One day they came after me. They stripped me,molested me,and groped my fat. Similar thing happened at preschool, at age 6, minus molesting. My own dad would grab me by the ass throughout my childhood and tell me how fat I was. He wasn't the only one who did such a thing. Last time such thing happened was at age 12,a boy from my school grabbed my fat ass and when I started complaining he said that I should be grateful for any attention got since I was,in his words, hideous and fat. It was the moment that kickstarted my eating disorder.
To get back to the point, I can pinpoint the moment when everything started. I was 4. Totally spies was playing on the TV. It was the episode where a villain was plotting to conquer the world by making everyone fat by selling addictive cookies. Watching one of the protagonists gain fuckton of weight awakened both my fetish and lesbianism,however, it manifested slightly later. I started touching myself couple of months later and I have been doing it all the time i was alone while thinking of fat women. I got addicted to porn at 7 years old when I was left unattended. I simply googled "fat women " on a family pc and within minutes I fell down the rabbit hole of fat fetish models and fat fetish art. The rest is history.
