Jim, as the daughter who caused pain and heartache to my mother by my PTSD actions, Yes, I feel guilty for what I put her through.

I don't feel guilty for my actions because I know I am sick and was undiagnosed at the time. It hurts me to know that I hurt her. For that I feel guilty and try daily to make it up to her.

It is the guilt of causing her parents pain and sorrow that I think is bothering your daughter more than the actual deed itself.
