Body positivity

I'm having a really hard time being comfortable in my own skin. I'm 15 and I'm going into my sophomore year in high school and I'm so self conscious of my body. I usually don't take pictures of myself in a bikini cause I absolutely hate my tummy and my thighs. I've been bullied for my weight and my looks for a few years. I've been called fat and ugly for the longest time. So i was just wondering what you guys thought. Thanks❤❤
