I second Diane B's answer.
Many years ago, when I was a Christian (I am not, now, but not for the reasons I'm going to mention here), I found myself faced with the raw reality that my drug-addicted husband was not going to get himself better. He wasn't going to hold down a job for any longer than a few months.
In short, I had to accept that I'd made a terribly bad decision in whom I had chosen as a spouse, and that I would be facing certain ruin staying with him.
I prayed, a lot. Nothing happened. I went to counseling and got to the point that I had the strength to do what I needed to do. I didn't want to be divorced, but had seen enough to know that I didn't have many other options because the ONLY person who could change my situation was me.
I prayed with my feet and left. Doors opened. A dear mentor loaned me money to move out immediately. Another job as a nanny with a good family opened up so I was able to work more hours.This was because I was willing to be open and honest, to ask and to seek. I leaned in and worked on myself, not depending on God to provide, but knowing that in Christ's love that there was *worth* in my being alive, *worth* in who I was and what I had to offer. Within a year, I had paid off the loan and met my current husband.
I didn't have a child to support in all of this, but if I had, I would have humbled myself and sought out every resource possible to help with ensuring his quality of life. When I was with my ex, when he was unemployed many times, I'd humbled myself and waited on line at the food pantry. If those families who had come upon hard times could ask, with humility, for what they needed, I could too.
I'm not a Christian any more, but it wasn't my bad marriage or divorce that changed that. I prayed, I sought, and I did. In the doing, I became a better and happier person. I hope you know that there are resources available. There are people who will help-- but we have to be willing to admit we do need help from them. It's okay not to have it all together. For me, my faith wasn't about God rescuing me, it was about seeing the intrinsic value in myself and deciding I was worthy of something better than what I'd been stuck in, even though I never could have known what that would be.
