i’m jealous of my friends..😞

so my two main friends are gorgeous!! they have both dated before multiple times, & they’re a little more developed than me in the chest area, & i just feel like i can’t compare to them. of course, they’re the best friends i could ever ask for, i just feel like i’m not as pretty as they are. i’m the only one in my entire friend group that’s never dated before & it makes me feel sad & unwanted.. any tips please? 😞
