Oh, I'm so sorry that your little one is struggling so already this year.
I wouldn't assume that the home situation isn't what is fueling things-- it's likely that it's a slow burn and that it is filling up his capacity for managing his anxiety... which is then leading to a reduced capacity in other areas.
I'm glad that today is looking better.
I'm also glad to help you craft/wordsmith letters via PM, if you like. I'm pretty experienced at the art of oral and written methods of advocacy, given that those have been the only methods available to us over the past eight years.
