Tony,
Truly Sorry for your current situation, and you took Right move by asking about it in mentor group.
Have you considered searching for a full-time job within your resident country? I don't think age 40 (or any number) makes any difference as long as you have skills that are required in current market. In this digital age, information on internet is abundant, so go ahead, take 1-2 days vacation (don't tell anyone about it), search on internet for current skills in demand, identify your skill sets for potential matches, and search for your new 9-5 job aggressively. If anyone asks about current work situation and family, tell them openly about it. Somehow, being honest is more powerful in convincing job interviewer that your need for job is fully genuine and urgent. During job searches, either surround yourself with positive minded people, Or just stay alone.
I am sharing these thoughts from a friend's similar journey. He used to talk to me a lot during his tough times.
Tough times don't last forever, so enjoy this ride as much as you can.
Best wishes, Good luck, and keep us posted.
