I did some research.
You mentioned that you live in northeastern Oklahoma, so I’m assuming you’re in a somewhat reasonable distance from Tulsa. It is possible that you could get an Uber to go from Tulsa to where you are rurally (for a pretty penny, of course). If I were you, I’d play around with the app and see if you can get anything. If not, try another service such as Lyft or a local taxi service based out of Tulsa. Here’s a list of some: m.yelp.com/search?cflt=taxis&find_loc=Tulsa%2C+OK
You can try calling the local ones and explain that you need a ride to Tulsa from where you are and that you are happy to pay or whatever.
Once you get to Tulsa, there is a Greyhound bus station there. The address is 317 S Detroit Ave, Tulsa, OK 74120. You can get pretty much anywhere you need to go once you get to the station. Make sure to buy your ticket in advance. They have routes to pretty much every major US city. You will need to dress conservatively so as to not be visibly trans. I know that it’s painful but when travelling on things like Greyhound it’s safety first. From what I’ve heard, Greyhound can be pretty janky and have some weird people, but it will get you to where you need to go since you don’t have a car. Just keep a watchful eye on all of your belongings and surroundings.
Make sure other people know about your whereabouts as you travel in case anything were to happen. It can be an online friend, this community, or anything else. Have a plan with them about what to do if anything goes wrong. It is always best to be prepared, even though the chance of anything nefarious happening is very low.
When you get to the state that you’re going to, look into the government programs. Blue states are a lot more generous with them than most red. You can qualify for disability because you have autism, so look into that. You might also be able to get things like unemployment, food stamps, and other government assistance while you’re trying to figure things out.
Also, please try to eat. It’s very important to keep your strength up in situations like these and not eating will make you weaker and your brain foggier. Even if you’re not hungry, just try to get something down.
I hope this helps. I’m really really praying that you get out of the situation you’re in safely and get to a better place. I promise you, you can have a much better life than the one you’ve been living. There are places where you can be yourself freely. There are people who will accept you for who you are. It’s not going to be easy, but I can promise you that it’s going to be worth it.
