You are me, as in same height, body type, not wearing heels etc etc . I shed all my insecurities just around when I was your age. I had extremely bad body issues( body dysmorphia) and self worth. And I regret hating my height and self so so much, because they were a source of depression for me. But I fucking love it. Its one thing that sets me apart. I would recommend working out, it gives you a sense of control that you may feel that you lack over your body, and it makes you feel sexy. And you can sculpt it other ways that you want. You likely have long legs, that's one of your keys to feeling feminine. I feel like growing my hair long made me feel feminine as well.Heels?- instead of thinking I am gonna look so tall etc, instead I think, do I like wearing heels? If yes? Then I am gonna wear them. I am tall, so like two inches won't make much difference. So instead of trying to fight it, I would say work with it. Look up those models on Instagram, they carry themselves with such confidence! Think of yourself like them.Self love has been the key for me.
