Jen, do you think perhaps his sleeping in and low mood is somehow related to his diabetes not being well controlled? I am not an expert on diabetes by any means however it would seem to me that not having one's physical illness properly managed would affect one's mood. Though as you say, it is up to him to exercise and also eat properly!

I imagine it was a very emotional farewell with your son! I am not looking forward to mine with Colin. He leaves for Afghanistan in 3 weeks.
