How can I get comfortable with my body ? I'm not considered the average body type?

[Music is love]

I'm 16 and 5'6 or 5'7 . I'm several inches taller than most of the girls at my school and it makes me feel like I stand out. I'm also pretty skinny , for my height I'm 5-10 pounds underweight and I just look awkward and lanky. I have really small boobs, 34B or 36A and I desperately want to be a C. My family members all range from D's to G cups !!! I also have a tiny butt. Social media portrays women who are sexy basically having the opposite body type of me. Especially in the black community, I'm expected to be curvy. I don't consider myself ugly at all, but I feel like I don't measure up in comparison to other girls. What should I do to feel better about myself ?
