Wow!! I can feel your worry and concern. Maybe it would help to go back to the Reading Behaviors and practice only those for a bit. Then move slooooowwllyy back through building stamina, and review the I Charts. Take away any choice of what to do that you have given them for a bit of time.
Sometimes we have to take two steps back to get a step ahead--it's hard, but necessary.
Keep us posted on how it's going.
