Please bless Barbara as she grieves the loss of her mother. It sounds like her sister + BIL are treating her terribly, so she's suffering from that too.
Then today, she fell partway down the stairs. She's all scraped up + bruised. TY that she didn't break any bones or hurt herself worse.
She seems terrified of making the landlord mad. He's actually a pretty nice guy, although I have seen him get testy sometimes. Help her in all her relationships, including with him.
Also, she is lonely. Help me be a friend to her + send other friends her way. Show me how else I may help her.
In Your precious name, amen.
