I am feeling guilt about my mom passing. I have said some nasty things to her in the past that I am so ashamed of and wish I could undo some how. God, I wish I could have been nicer, done more things for her. Helped her more the nursing home and hospice. Just a ton of stuff I feel I could have done better, been a better son. But now its too late and I pray for her and ask her forgiveness. Any advice?
