Yes my son just turned 17 yesterday. So far we have been very lucky as he tends to be fairly chilled. He loves school, does really well and thankfully likes hospital and blood tests, etc. The main issue we have is tiredness. Some days you can tell he just needs to stay home and chill, he gets really quiet and just stays in his room. It usually doesn't last too long though. i either leave him in peace or sit quietly in his room reading a book just to give him some company.
