Prayers needed

Hi All, I’m in need of prayers for my mom (Jestine) who has a heart condition & is care taker to her mother but now in a bad living situation within the last month. 1 month ago her 18yr old great niece showed up at the house with her belongings asking my grandmother where a shelter was bcuz her mom put her out the house for kicking her (she has fought her own grandmother & uncles wife previously after being disrespectful in their own homes while staying with them). My grandmother is 86 with dementia & told her she could stay with them instead of going to shelter (which she knew she would). Things started off ok UNTIL she’s now not wanting to follow house rules nor wanting to be told anything which is why she was put out of multiple homes before. She’s very disrespectful & has a bad spirit in her (possible demon) and is unpredictable. We all want her out of the house ASAP but my moms 2 sisters hv turned against my mom out of pity for the 18yr old saying don’t put her out into a shelter BUT she’s highly manipulative & comes off sweet & innocent like she’s done nothing. If she’ll assault her own mom & grandmother..she’ll do the same to my mom when angry. Please pray for my moms protection & the situation for something to work out & her to leave ASAP without harming anyone. It’s really sad & scary my mom & grandmother don’t hv peace in their own homes after trying to help her but my Grandmother didn’t know aby better due to her mental state.
