Its the significant distress or impairment which is key. As an example most people will put off doing things like sorting out an issue with their electricity provider, but I took that to the degree where I only sorted it when someone literally turned up on my doorstep to disconnect the supply.

Throughout my life I've found myself in situations where most people would go "well, this seems to be getting out of hand" and just carried on, getting ever more stressed and angry and seemingly being unable to get on with fixing it, whilst variously losing jobs, friendships, and a marriage. It was honestly a huge relief to discover the likely cause is ADHD rather than just being a failure of a human being.
