I know you don't want to separate them but i wonder if you should propose that S9 to come stay with you. This situation is so unbearable for the kids. I wish you had money to hire someone who will really protect them! Can you take a part-time job just to pay for that?
I believe I will see the bounty of the Lord in the land of the living. Wait for the Lord with courage. Be stouthearted, and wait for the Lord.
