Losing weight

I am 5'3 and weigh 192 and I am so uncomfortable about my body. I literally hate is so much. I wanna lose weight and i have tried so hard, I lose a few lbs and it comes right back. I can't really eat healthy bc I don't buy or fix my food and my mom doesn't cook/but healthy st all bc my family besides me is so picky and hates all the healthy stuff :/ I know to cut sweets and sodas, I was just drinking water (which helped me lose like 5-6lbs) but recently started to drink soda again bc I gained 3lbs without the soda
