There is something you can do for your loved one without hurting yourself............pray & ask The Lord to deliver them. Pray they get to the point where they are praying to be delivered. Deliverance is something we cannot do for ourselves. We must ask & then wait on The Lord, it will be in God's Time not ours.
Praying for yourself & asking is necessary before God can deliever us no matter who else is praying for us. It is btw God & you.
