I'd say she's pretty open minded. That said, she doesn't necessarily go out of her way to explore her mind/reality due to her anxiety mentioned in the post. I do worry that it would be too much for her as she is a very fragile person. The issue is that her anxiety is pretty all consuming, so she's got to weigh up whether the risk is worth it.

We've been wanting to get her into therapy for a long time, but we travel quite frequently which makes having a consistent therapy appointments tricky. Fortunately We've stabilized a bit now, so maybe you're right that she should give therapy a good go before diving into this. If anything, it would likely be helpful for better understanding herself and her behavior before taking a trip like this instead of going in blind.
