I am really sorry if I came across as judging you or as implying that you are being a difficult parent; not at all; I don't think parents have any vested interest in being difficult or in complaining to/about schools. I also really do understand your disappointment in not having the problems fixed, as you have obviously been working to get them addressed for a long time. Also, you should absolutely not feel guilty about demanding safety for your child.
I think I am just so anxious for this branch to succeed, because of the horror stories I have been reading about some schools here on QL. I just want this new school to have every possible chance at success.
I sense fatigue in your comments, and I think it could happen (and indeed has happened) to other parents as they face problems with their children's school. I wish your child all the best. I hope s/he is happy at the new school. I guess, as parents we can only try, right?
