However, Kloos said that after coming back to the Church, it was still hard for her to feel fully welcomed, because those wounded by abuse were not yet prayed for during Mass.
She began sending letters to her bishop in the Diocese of London, asking him to offer a Mass for victims of clerical abuse. For seven years she wrote with the same request, and she also made rosaries which she sent to clergy asking them to pray for those who have been wounded by abuse and who are far away from the Church.
She spoke of the importance of receiving the Eucharist, and lamented the fact that there are "thousands of people wounded by clergy and generations of people who may never enter a church again because of the irreparable damage caused by abuse that separated them from the Eucharist."
There are many people who are addicted to drugs and alcohol, who struggle with mental health problems, families have broken up and there have been suicides, "all caused by abuse," she said, stressing that this is why prayer is so necessary, yet often times the issue is still too taboo to talk about publicly in the Church.
"People just did not know how to deal with this," she said.
"It is uncomfortable. I understand this. It hurts to acknowledge and talk about sin and abuse in the Church, but only when we pray together and bring the darkness into the Light, by asking God to help us, can communication, forgiveness, and healing occur."
When the Pontifical Commission for the Protection of Minors was established in March 2014, Kloos began writing to members voicing her desire for a day of prayer for abuse survivors. She also sent them artwork she had made as a way to heal and show how she found hope.
In 2016 the commission recommended that a day of prayer for abuse survivors be established, and Pope Francis accepted the proposal, asking that it be organized at a local level.
In the London diocese, the day of prayer was held on the feast of Our Lady of Sorrows, and "it was beautiful." Kloos voiced her gratitude to the clerics of her diocese for organizing the now-annual Mass, saying she believes they are doing their best, and are trying to move in the right direction.
"They are good people in my diocese and I care about them," she said. "We have really dedicated clergy in the diocese. I feel it is important to focus on the positives and when people change for the better, then we should encourage them because a change of attitude and behavior takes time."
Kloos has maintained close correspondence with members of the pontifical commission, including Fr. Hans Zollner SJ, head of the Center for Child Protection.

Commission members "need encouragement and positive support from people, especially clergy abuse survivors," she explained. The members "work hard and need lots of prayer and support. I want to give them this support as a clergy abuse survivor and thank them."
Kloos said she believes that while there is still more that needs to be done to prevent abuse and help survivors heal, the Church has made progress.
Citing guidelines and safety policies that have been put into place as well as suggestions for tougher screenings for Church employees and free counseling for clergy abuse survivors, Kloos said these are "huge changes" that she appreciates.
She also pointed to a course organized by the Center for Child Protection on the dangers of abuse in the digital world, and the degrees in child safety being offered by the Pontifical Gregorian University in Rome.
Kloos voiced appreciation for Pope Francis' recent apology for having made "serious mistakes" in the Chilean sexual abuse case.
Francis "had the courage to admit what he said was wrong to the Chilean abuse survivors and is meeting them now to apologize personally."
