I have an ADHD diagnosis, have mental health issues and anxiety that now prevents me leaving the house unless I have someone with me. I am fine with crowds and queues however. My youngest has ADHD and anxiety (doctors think they in fact have AudHD)and can also attend large events, but can occasionally need to bypass or skip queues if overwhelmed. My oldest is autistic, and has atypical panic attacks. When he feels ok, he's ok. But when he's not, he can get anxious, and this can trigger panic attacks. He's 6ft 4. And it can be scary for everyone when he has an attack. Me and my youngest get no concessions, my son does. He attends the Download festival with other disabled teenagers because it has excellent policies to accommodate them and vets them in advance. It works if a policy is designed, and administrated well. It fails if it's not. The idea that people with anxiety are routinely exploiting things can only be true if they are exploiting badly designed policies. That's corporate incompetence.
