Dumb ass bitch here

Am I the only person that developed issues with food out of spite. My family but especially one of my grandparents was obsessed with health food and was always not pleased with my sister and My weight so I made sure to eat a shit ton just as a screw you Like I would feel completely full but I would keep eating slowly because I felt like stopping would be giving up and letting them win and control me. I always hated my body and weight but that spite kept me going until one year when I realized if I eat too little that will also freak them out. Now shit just kind of fluctuates back-and-forth but it all started just cause I was pissed off.
