Haven't heard back from you Megan - is Going Home the one you wanted? There's a spiritual,The Troubles of The World, that includes the words, "Soon I will be done with the troubles of the world, I'm going home to live with God." It's one of my favorite songs in the whole entire world. Can give you more info if it helps.Your mother must be very brave and wonderful. I'm all for planning one's own funeral. I know a woman who had terminal cancer and held her own wake so she could be there to hear what they would say about her :)
Take comfort from her courage.
