Anxiety about my weight

Soph • 17 / in a relationship💕
It's not my boyfriend who sees my body that I'm anxious about its everyone else, you know I have cellulite, stretch marks all over my butt and thighs. My thighs also are not thin and slender and my stomach isn't fat butt it's squishy. It's almost summer here and I'm just so insecure about what I look like it makes me really sad and cry a lot but I don't think there is much I can do
