Girls, who has ever stopped or is going to stop breastfeeding?

Girls, who has ever stopped or is going to stop breastfeeding? My daughter is 11 months old and decided to try weaning from the breast at least for daytime feedings. She cries, whines, begs...it's so heartbreaking. And now I feel guilty ?. I don't know what to do, whether to go all the way and not give her during the day, or to give up because it hurts?.
