Hard one. I remember a quote from a Holocaust survivor that puts things into perspective for me.
"People disagree over whether a glass is half-full or half-empty. I just give thanks that I have a glass."
What makes that really hit home for me is that I found out that my Mother's maternal Grandmother was Jewish, so I would be considered Jewish too. I am glad I am here to suffer GID in the first place, you could say.
Until you are in a position to do something about it, just take care of the body you have, and enjoy what it can do. The fitter you are, the easier recovery from surgery will be for a start. That's something you can consider you are working towards.
Putting one over on the guys is something teenage girls like to do too, isn't it? If they don't twig, more fool them!

If you can find a Best Female Friend to come out to, and confide in, you can start the process of learning all the things you have missed out on up until now.
We can't rush things, which on reflection is probably a good thing.
