I'm not within your age range, unfortunately.
I am however a trans woman in rural Kansas (it's the state in the dead center of the United States).
The 3 things I find most difficult about being trans while living somewhere rural, and why they are difficult in my experience are:
1) People out where I live (Rural Easter Kansas) are Ignorant. People here have almost zero knowledge of trans people, or the issues we face. Not only that, but they want to be ignorant on many issues (not just trans issues). This place resists change of any kind. If you try to engage them in dialog on a topic they do not wish to know something about, you are treated as being, frankly, insane for ever even bringing the subject up.
The one time I ever heard anyone in town discussing something about trans people was because someone 'saw a ->-bleeped-<-' at Wal-Mart 70 miles from here. They were shocked that anyone would do that, stated if anyone like shouldn't be allowed in town, and were 'furious that their tax dollars go toward such disgusting deviation'.
While I'm thinking about it, anyone able to tell me where this government assistance in the U.S. is for trans people that they were talking about?
2) Lack of law enforcement. As I said, the nearest police station is 20 miles away. It's a big deal if a police car even drives through town at all. So, assuming the authorities would actually assist a trans person who is, say, being attacked by someone or a group of people due to transphobia, help is a long way off. Dispatchers often argue over if my city is in one of two counties and often re-route calls to the opposing county who will then send you back to the other ... Getting the authorities to respond to a traffic accident alone is a serious pain, but this would also be a further delay in assistance. The only way to insure your safety as anyone in the LGBT spectrum is to live a closeted life as long as you are here.
3) Lack of resources. I have to drive a good 60 miles to reach my therapist, or the nearest LGBT center or PFLAG organization of any kind, making the net my only real source of information outside of my therapist at the moment. To my knowledge, I would have to drive two hours away to find a doctor capable in assisting with HRT (which I won't start until I move away from this god awful place). There's literally just no resources here for L,G,B or T people.
What would help? Honestly ... I don't know that anything would help, short of moving away from here. Thankfully now that my wife knows, we are slowly trying to find a way to do so.
Outside of that? I don't really know. These people have no knowledge on the subject (and many others), don't want to know anything about it, and are proud they don't know anything about it. It is going to take several generations for this place to change ... if at all.
