While attending a local convent school, she smelled a wonderful odor on first beholding the host and begged the Abbess to be allowed to partake of the Eucharist with the nuns.
Margaret slept little, often due to severe headaches, ate little, kept frequent vigils, engaged in long periods of fasting and continued her self-mortification.
Margaret had visions of Christ and of the Virgin Mary and felt angels holding her up when her austerities left her too weak to stand.
Many miracles were attributed to Margaret, such as making whole some smashed eggs so the family would have something to eat, and saving her sister who was on the point of death during childbirth.
Her austere lifestyle took a toll on her health and she was eventually bedridden, experiencing great pain, fevers and convulsions, all of which tribulations she bore with grace.
