Help with body image

So I’ve been struggling lately with how I look. How am I supposed to feel good about myself when there are thousands of people on Instagram who have the smallest waist, big perky boobs, and a big butt?? I know I’m wrong for comparing myself to them, and I know many of them may edit their pictures, and they post the best of the best photos... but still it’s mentally defeating to look at. I hate social media... I feel like all it does for women is create unrealistic expectations of what a women’s body should look like.
