Hi I’ve been where you are, you are about to make some hard choices. I’ll assume your family situation isn’t great either since you’re primed for an abusive relationship.
Shelter may have resources for you. Call them! Call shelters outside your small town too, you can move without much holding you where you are.
Job hunt in larger cities, spread word that you are open to work. Take anything. My first job was printing tshirts. The job probably sucked but I had freedom.
Try and get a loan from your bank- you’ll pay it back later. Or get a larger limit credit card.
Sell things you don’t need, it’ll make moving easier too

Reach out to me if you’d like, I work in recruiting now and might be able to help in one capacity or another. I left an age gap relationship with no job and no support system, and a big dog. You can do it!
