That sounds really tough. Does she have a therapist? If not, that might be something for her to try if she’s open to it. It would also give her an outlet while you guys are away.
A doctor could potentially prescribe as-needed anxiety medication that could help with the choking episodes although it seems like gradually working towards becoming more independent might be a good idea overall. How does she do when you leave for a few hours or a day? Is her anxiety more about being alone at night?
Those are just some thoughts. It’s hard to give definitive answers because we’re all so different. There was a time when I was afraid to be alone but that was more related to trauma and genuine safety concerns.
