@learningtolive,
Omg, I've *been* there, with the embrassment and shame/humiliation. I used to see (mostly older) transwomen and couldn't help thinking there was something wrong with them, and hating the idea that I was anything like them. I think what really helped me de-stigmatize it was finally accepting that we are the same. We suffer from the same condition. I guess in my head - because I thought being trans was "weird" - I sorta separated *myself* from it, and looked at myself as somehow *more* woman than other transgirls. It wasn't until I finally looked in the mirror and said "this is who you are" that I finally came to accept myself, and the fact that I'm trans. I'm not saying that it isn't still a struggle, and I, too, am still working on telling my family (but now it's mostly just because I'm worried about *them* thinking I'm a freak, not cuz I feel like one) but it's one I am slowly overcoming.
I now look at transwomen and don't see them as "women who used to be men", anymore. I see them as women who finally took that big step to become themselves. And whether they're young, old, "pass" or "don't pass", doesn't matter - I applaud them for their bravery.
It may help you to watch YouTube videos, as well, to see how many transgirls are just totally normal people, like anyone else. I have a zillion subscriptions to trans videos!
