As I was thinking about forgiving people who have hurt me, I began to realize that sometimes the central person I have to forgive is myself. Is it acceptable to consider forgiving myself?
Yes, and the process of forgiving yourself is described in detail in my book, 8 Keys to Forgiveness (W.W. Norton & Company, 2015, available at amazon.com). The difference between forgiving others and forgiving yourself is that in forgiving the self, you also need to go to those who were hurt by your actions and ask for forgiveness. So, you forgive (the self) and seek forgiveness (from others) in self forgiveness.
