YES! Get to the city any way you can. If you don’t have any money see if you have something to trade or sell. Go to a homeless shelter, some have case workers who can help you. Some cities have shelters just for victims of abuse where they make sure your identity is hidden and they can help you get setup with housing and other assistance. You’ll likely have more options since you’re disabled. Your family is less likely to go to a city to find you. You deserve way better and I hope you find peace.
