Why does God make people transgender?

I've been thinking about this lately. I've always thought "God doesn't make mistakes" in regards to making people LGB. Gays, lesbians and bisexuals (like me) were created that way by God and embracing that helped me a lot.

So why does God make people who have the wrong body and biological sex? That seems like a "mistake", but as noted God doesn't make mistakes. If I were trans I'd be angry at God honestly for making me that way. With the suffering they often go through, I can't see it like being bisexual which I accepted as a blessing. Having the wrong body and such a traumatizing condition I don't see how that could be a blessing.

I guess none of us can know, but I wonder so much now.
