I felt sad last year when we could not get DD's teachers and school to do anything positive, despite our best efforts to go along with their suggestions and not be too demanding. I think there's a Japanese word that describes regret at a situation involving waste (mottainai?) that expresses it better. Even when it's not your fault it didn't work, it's still sad when things don't work out that could have worked out great but for other people being unhelpful.
Congratulations on making a positive step; I hope things go well for you all.
