Hey, Heavyhauler, and again, welcome to Psych Central! Alas, sometimes we do the best we can and things still go wrong. We are only hearing your side of the story, though.
I can certainly understand how you would feel lost. None of us is perfect. Is there anything else you can think of besides a lack of trust that led to your divorce? Maybe if we knew more about things, then we might be able to give some more advice.
How are you doing with your health problems? Are you okay? I'm wondering if you could afford to at least find a job that's closer to your kids.
