I don't have a ton of advice for you, but my H has ADD, and talking to him about serious stuff like emotions can some times be a trial, because he fatigues easily. This sounds like a really big challenge. The only thing I can really say is try not to take it personally. And honestly it is up to your T to schedule at times that work for her, and its up to her to manage things in away that are helpful to her. Unless think kind of thing turns into a reoccurring pattern I wouldn't worry about it.
