I don't think she is on the verge of a breakdown, so probably the experience could help ground her/round her out. The problem is, she's resisting all of it by engaging in immature bickering and arguing over semantics. It's really her choice to get anything out of it at all.
I did say in the past that I think she has not finished transitioning internally as she is far too cognizant of appearances and seems to be caught up in other people's reactions. But, if she is generally immature and tends to lack self-awareness (again, superficial thinking), then there's not much more psychological work she could do to evolve upward if she is constantly trying to mitigate her neurosis by expecting everyone else around her to treat her like a crying infant. She'd then be more concerned about the symptoms of a problem rather than trying to address the cause of a problem instead.
She chose to go go on, so probably subconsciously she is looking for a way to be pushed out of that cycle. After all, we all tend to want to do things the hardest way when our minds are really set.
