LDS here… (the old forum provided a way to display one’s denomination, but I don’t see that in the new setup.)
In the LDS Church there is a path for her to get assistance. First, she should do what she can to be self-reliant. If she is unable to pay for her own needs she should then approach her family for assistance. If resources from family are unavailable or have have been exhausted then she ought to go to the bishop and ask for financial assistance from the fast offerings. I’ve been taught that if you don’t have enough to pay tithing and bills, then pay tithing and seek assistance from the church. LDS believe that tithing is the Lord’s money, so it’s inappropriate to spent it on your own needs.
Also, if she is in a financial bind she ought to be communicating her need to her home teacher and visiting teacher. These members in her congregation have a stewardship over her and should be working with her to resolve issues she has. I hope this helps…
