Can you work as a consultant in these industries for now? That type of industry is awash in consultants and I would imagine that you might have the proper skill set to become one. That will give you immediate access to money and time with your daughters. This will be a good stepping stone to get back to training at some point and allow you to travel.
Talk with your former colleagues and bosses to put out feelers.
P.S. I have a cousin who works in a very well-paying job for a major oil company and he works from his home. He travels to the company headquarters for meetings. Otherwise all of his work is done from his home office.
