The trap is trying to externalize the diagnoses as a get out of jail free card that can be used to justify avoiding hard changes and difficult work. The more difficult version of this is when someone tries to externalize the responsibilities of their diagnosis on others. I've seen a couple situations where someone got an ADHD diagnosis and then took it straight to their employers expecting to receive more forgiveness for late work and mistakes, then getting angry when it didn't change their company's expectations. It's a hard conversation to have with someone who thinks the diagnosis is going to relieve the weight of all the problems they've been facing, when in fact it's only helpful for identifying what they need to work even harder on improving and coping with.
