I'm sad you find yourself in this difficult position. Sadly it's the same old story of too little too late as regards the elders. The situation I had to cope with myself (nothing to do with child abuse thank god) showed up the elders MO very well.
It's the 3 wise monkeys: Hear no evil, see no evil, speak no evil. The carpet in the hall is very lumpy im suprised people can walk on it with all the crap swept under there.
What they want is for you to shut up and "stop obsessing" over it no doubt. But what they dont seem to understand is that if it was handled better and more sensitively then you'd have every reason to comply with that directive.
They wont care that you leave either im willing to bet, ...because it will be your fault in their eyes
Painful as it is now and the severe wrench in your life, it will get better and you will feel better. Says me of the wish I could quit class...
Cheers
