I keep thinking that I have a really masculine frame, but it helps to look at some of the more manly/thin women around me and compare myself to them instead of looking at the most feminine women I can find. Then I can go:
"Ok, I'm 6 feet tall, but she's got 3 inches on me, easy. This isn't so bad."
"Yeah, my shoulders are, like, 22 inches broad, but hers are almost the same."
"My hips are way too narrow, but at least they're wider than hers. I think my ass is a lot bigger, too."
That, and remembering that HRT will help with some things, keeps me sane. I try to think of myself as a really, really butch amazon, instead of as a guy. I'm flat-chested, not man-chested. My big hands are elegant, not unwieldly, and my toned muscles make me a strong woman, not an athletic man.
Trying to stay positive and see the good side of things. I'd constantly be depressed if I didn't.
