Hi Harry,
Your post confused me a little bit, as your statement almost sounds like retribution rather than reconciliation.
She wounded us, and we can't really express it to her. Well, sometimes we can, but as soon as she smells the slightest accusation, she moves into defense. It feels like she doesn't take responsibility to what she did to us. And it would be so good to see her grief about her causing us to suffer.
I hope you are seeking reconciliation. I have PTSD and my behaviors have hurt my husband and my children. But we don't discuss it in the "spirit of blame", but in the "spirit of healing". They have identified the specific behaviors, how they feel about it, and then set boundaries to ensure their feelings are not negatively affected.
For example, my isolation really caused my family discomfort. They couldn't understand why I was "mad" at them or what they did "wrong". Once I explained that I wasn't mad at them and they didn't do anything wrong, it was just my means of coping when I felt overloaded, things improved dramatically. At the same time, I did acknowledge how the behavior could be interpreted that way. Now I just let them know when I need "down time". They understand it, do not take it personally, respect my privacy, and continue to do what they want and go about their day. No one has to worry, feel guilty, or confused.
Perhaps family therapy would help, and sometimes a third party is invaluable when addressing emotionally charged subjects. It is wonderful that your family is still intact and they is quite an accomplishment when dealing with PTSD. The bright side to this disorder is that by improving communication, it can make an entire family stronger, closer, and healthier.
Wishing you the best.
Debbie
