For many, confidence in themselves was taken away. People were made to believe they were inferior to white people. There is still a lot of resentment over this. Many people speak of rejecting their full blood mothers and brothers and sisters as a result of what they were told about full blood people at the missions. Many remain in denial about their connection to their full blood family.
People have to live with the effects of being denied a normal loving family life.
Many people have trouble bringing up their own families because they have never experienced that kind of life. Many people have found their families again but it is not the same. The relationship was severed and it is difficult to establish a mother-child relationship when you have been separated all that time. There is a gap that is there forever. To compensate for this, many people formed very strong bonds with the other children - they became like brothers and sisters to each other.
