Colleen,
It has been a heck of a week for you. I'm glad that the school is willing to include you on that conference.
It's so difficult when you haven't a clue just what you are dealing with - however, it's a bit too soon to fear for your young one's future. He's only 6. He has a lot of growing, you have a lot of exploring to do.
Additionally, you have no idea as to why the teacher is so frail as to be looking at quitting. She may have personal issues of her own - difficult child may not be the problem at all. Don't personalize other reactions or perceived reactions to your difficult child. It's simply not worth it.
Don't let yourself get ahead of the game. Deal with the here & now; the future is just that - the future. We cannot change what will be - just what is. :warrior:
