Just checking on you.....I'm so sorry about your niece. You are doing through quite a lot right now.
Here's a prayer for you to use:
Father, No matter how angry, deserted, disappointed I feel, Your love will never let me go. You will provide Your sustaining courage regardless of the future. Please grant me and my loved ones courage for whatever lies ahead. Help me to remember that You do understand everything about me, and want me to come to You laying all my burdens at Your feet. In Jesus’ name, Amen.
