CTH, take this for what it's worth but I have a suggestion.
You have mentioned in the past that when you talk to your sister you 'have' to go over the whole D thing and your feelings with her. You've also mentioned that about seeing people you haven't seen in a while or getting together with other D'd friends and having that in your convo.
It might help to stop talking about it entirely. If someone asks, there is no law that says you have to hash it out with them. A simple, "All is going well." will suffice. The less you are forced to bring it to the forefront of your mind the better able to put it behind you.
Just something I've found to be true.
