I don't know what advice to give her, or what help there is. She's scouring Craigslist looking for rooms for rent. Not easy with a kid. She's looking for any work-from-home jobs so she doesn't have to worry about child care. Most of those are scams. How can she get out of where she is and into somewhere else that's safe? I don't know if the ex's mom and her son count as abuse (the ex didn't do anything to stop it, and at times was outright, unquestioningly, verbally abusive to her, especially when he drinks), and if they do, what help there is. She's having really bad panic attacks over this that's affecting her health horribly, and she's worried about her son now mimicking the crap he's seeing his dad's family do (he hits, and basically acts in a way a 2-year-old in a stable, good situation wouldn't even do as play).
Please, please someone have a magic solution, and if there's no magic, then some leads.
