Primary aged DC has anxiety and possible ASD. There was an incident at school midweek where the class pranked him by pretending not to be his friend and ignoring him for most of the day, and were calling him shorty, shortstuff etc.
It's really, really affected him and triggered a spike in his anxiety. He isn't eating (have a separate thread on this) and is extremely tired to the point he can't get out of bed this morning. He refused school after the incident despite learning it's a prank. DC is an extremely sensitive and empathic child, and would never do a mean prank like this on someone else. But how can I help him build emotional resilience, to help him understand there are mean kids out there who do shitty things and worse things in life will happen. He cannot let every little thing affect him so greatly.
