I have also been advised to forgive my abusers, not for them, but for myself. Because I will not be able to move forward in my life until I let go of the past. I can see that's true for me, as I've been fighting these memories and emotions for over 30 years & having healthy relationships has been a HUGE challenge for me (another great effect that my failure to forgive has had upon my world today).
I *wish* that I could simply forgive and feel better. But, I am unable and unwilling to forgive still. I have met a couple of people, over the years as a PC member, who were abused in the past, struggled with life, and were finally able to forgive. That gives me a teensy bit of hope that I will be like them soon.
Very best wishes to you.
