Hello everyone. My son recently took himself off on his first ever train journey alone, sprung on me at very short notice but he managed it thanks to mobile phone contact, the internet proving us with train times, changes of platforms info and lots more. He had a great time meeting up with friends but at some time on the train he had a panic attack in the loo and couldn't bring himself to come out for half an hour. People banging on the door only made it worse and things could have turned nasty. Fortunately he was ok but has anyone got ideas regarding some kind of card or information sheet that he could carry to show people his problem. Something to give to people in this situation to help them understand if things get out of hand.
