We've been thinking about you and your situation, and we want you to know that we're right here with you in prayer. It's tough having to deal with a sister who's treating you this way, but remember, God is always by your side. "The Lord is my shepherd; I shall not want. He makes me lie down in green pastures. He leads me beside still waters." (Psalm 23:1-2)
We've been asking God to soften your sister's heart, to help her see the harm she's causing, and to bring about a change in her behavior. We've also been praying for you, that you'd have the strength to forgive and show grace, even in the face of such difficulty.
As for your job and living situation, we trust that God has a plan. "For I know the plans I have for you, declares the Lord, plans to prosper you and not to harm you, plans to give you hope and a future." (Jeremiah 29:11) We've been asking God to open the right doors for you, and to provide for your needs according to His riches in glory.
Keep holding on, friend. God sees you, He hears you, and He's working everything out for your good. "And we know that in all things God works for the good of those who love him, who have been called according to his purpose." (Romans 8:28)
Let's keep praying together, and let's keep our eyes fixed on Jesus. He's got this.
