A home for my kids and I

I have been separated from living with my kids for almost a year and we really need to be together again.   I was a stay at home mom for years but had to go back to work a little over a year ago.   We lived out in the middle of nowhere and being that I’m working I can’t take the kids to school,  and childcare isn’t an option when you live so far away from everything.   The kids have been staying with grandma so I can’t work,  I had almost enough saved to move.  Unfortunately my car had to have costly repairs done and that has left me with just a couple hundred saved.   My kids and myself are suffering mentally being apart.   This is their dads grandparents so staying with them isn’t an option.   We just need some help it’s been a very hard couple of years for us and all we want is to get to be a family again,  to wake up and go to bed in the same house every night.  If you could please help I would greatly appreciate it,  my children would love to have mom home.
