Everyone around me starts treating me badly ever since I gained weight?

my sister says my existence is disgusting and she randomly shouts at me and get annoyed from me

and i feel everyone loves me less now , or accept me

last month i tried losing weight bc i have a big event and i lost some weight but i did it in a wrong way (basically starving) and i gained all weight back when i started eating one or 2 meals a day and i usually binge then starve again and the cycle never ends

how do i feel great to get motivated when everyone around me make me feel bad about myself? it's really messing me up

on the other side , i know a lot of overweight people who are liked and supported by their friends and they seem beautiful and give off warm vibes , is the problem from how i feel about myself? bc they definitely feel good about themselves while i keep judging myself and EVERYTHING on my mind is about dieting , i try a lot and they seem to be relaxed about their weight
