NO BOOBS?!

How do i feel confident with my small boobs? i can't maintain cleavage. and i feel like the media, ppl, and everyone just seems to highlight that boobs are the best thing and you need to have them. it just makes me extremely insecure. and if i want to be really honest, sometimes i feel threatened by other girls because they have it. it makes me feel really alone bc everyone around me has boobs. thanks. pls help
