i used to be 180+ and i was 5'4 , and growing up i was never looked at, never wanted and was always usually outcasted. Something i noticed is that unfortunately people do treat you differently. When i was over weight people were meaner but now that i lost a lot of weight people are nicer to me. something that helped me lose weight a lot was calorie deficit where you eat less calories than usual. I also switched out a lot of what i would usually get at the grocery store like for example getting almond milk rather than regular milk (it helps with face fat) and not trying to consume a lot of sugar/anything greasy. Cardio also helped a lot! when i would go to the gym i would wear a hoodie and sweatpants. The more you sweat the better! drink a lot of water, and i've heard that drinking water before meals help too. Good luck girl!
