They weren't being bratty, immature, or idiots. They seem to have taken up the throne when they were very young, Celestia in her teens and Luna in her preteens. They were also training since they were kids, we know Celestia couldn't exactly play with her friends very much. When kids are given too much responsibility too soon it results in their emotional growth being stunted.

Also, we've seen hints of this before. How do you think Luna got banished? She didn't just randomly decide to not lower the moon, there were probably days upon days of slow build up in resentment. That combined with the stress of the battles that apparently took place within a year and stunted communication skills when it came to talking about their problems and possibly exhaustion and you've got a much more intense version of what happened here.
