The two most important things we can do for our loved ones are to pray and love them back to life with God. We don't need to focus on changing them, convincing them that they're wrong or going to hell because of their sin, or preach to them. Love them as you always have even though it may feel very awkward to you and pray for them continually. Try to keep in the forefront of your mind that God loves them more than you do, and He wants His best for them as do you. Let Him draw them by His Spirit while you continue to love and pray.
Have you experienced these? I have and then some! All are completely normal. Don't give up! There is hope!
