I would have kept going and not looked back.....if she needs money...let her sell her Lexus and take the bus.
Let her know where there are places that can help her. There are several food banks in my area and I would direct her there.
Don't know what it's like there now but I was stationed there a couple of years at Udorn in the 70's. Seemed like a nice country if not a little wild. You could do or see anything you could think of there. I would go back to visit again. Overall? A nice country.
Unless it's in the news ... I don't usually think about Thailand
