This is part of what a family is about, not just love. It’s knowing that your family will be there watching out for you. Nothing else will give you that. Not money. Not fame. Not work.
Accept what you are able to do and what you are not able to do. Accept the past as past, without denying it or discarding it. Learn to forgive yourself and to forgive others. Don’t assume that it’s too late to get involved.
