I think even a lot of cis-gender girls look at other girls and envy them. I think a lot of people have what they don't want, and want what they don't have. It's not unusual.
HRT takes time. Cis-gender girls took a lot long time to develop into women... there's no free lunch... we're going to have to put the time into it too. I still present as male in public, and my internal struggles are a secret from friends and family. My support group is limited too, but I'm doing what makes me feel best, and I am continuing to make progress behind the scenes. You're going to make it happen too if that is what you want.
I do think cosmetics, advertisements, and our social standards heavily exaggerate what is feminine. While I was in a serious relationship several years ago, my beautiful (ex) girlfriend was comfortable enough around me to remove her makeup. She was still gorgeous, but that is when I realized that she did not have the dominating features that I was expecting. A lot of people throw on a mask and, for some reason, we believe these characteristics are completely natural, but they are not. Anyone can pass... what's interesting is that I am the last person to notice these changes despite looking for them. Again, I haven't even expressed myself openly, and people are telling me changes *they* notice (before me). Don't be too hard on yourself.
