Loved ones who die, do they become Guardian Angels?
Your loved ones will certainly come around you and help in any way they can. They are not actually angels which are a separate creation of God. But if you call upon them at night, ask them to visit you in dream state, they will come. And if you feel their presence then they are around you, talk to them! Tell them what you need, ask them to make things right, and give them errands and little jobs to help your life.
