Glad things are getting better for you. It's such a rollercoaster of a ride, all the ups and downs, glad the school are receptive to your needs.
Good to see that your son is keeping up his football, the sooner you get in routine or back to normal as you possibly can the better. With regards to the highs and lows we also experienced that (still do but less frequent), it will get better especially if he has stopping eating for England as we experienced.
