it just appeared out of nowhere. nothing happened. we went to the royal show had a great day with his family. wen we got home he was very withdrawn and just sat outside staring at the wall. i asked what was wrong - he said just tired (we had a big day) and he hasnt shaken it since then.
he hasnt had a check up with a gp either he hates going to the doctor and avoids it at every opportunity. he will only go when he is really really physically sick.
