Both of my teenagers have aspergers and I’m finding it very hard lately to cope with Ds 14. He has an obsession with a particular event and wants to travel abroad to take part it in. There’s no way it will happen but he’s constantly trying to explain to me that he has to go and he will sell x and x to afford it. I feel very sorry for him because it’s all he can think about but I can’t keep repeating no and the reasons why over and over. Every day it starts up again. How do you cope?
