Having steady faith

My dear friends keeping your faith steady can be difficult.  Currently, there is a situation with a family member that is testing my faith.  This individual continues to make bad choices in her life.  I am unsure if she realizes how her choices affects everyone else in her life.  I believe that she has an illness and cannot help what she continues to do repeatedly.  It is difficult to hear about, and I am thankful that I am not witnessing it first hand.  I am trying to have my faith steady.  In times like these, I feel hopeless and helpless.  I do not know what to say or do in these situations.  I pray that if I am to do something that the Holy Spirit would nudge me.   I am trying to believe that God has got this situation under control despite it looking like it is completely out of control.  I am trying to believe that He has her in his hands and is carrying her.  This has been a long, many years of addiction for this individual and many years suffering from depression.  I pray for this individual for strength and healing.  I pray that she realizes how important she is to God and that she is loved.  I pray that she realizes that there is absolutely nothing in her past that God does not know about or cannot handle.  I pray that she can let go of whatever negative thoughts flow in every day.  I pray she can get past this rough period.  Please pray with me!
