I'm writing about mental health counselling and how centres are often fully booked. I then say: "I'm sure many others have the same story, and crises that deserve immediate attention are left to -- "
What's the word I'm looking for? It's like exacerbate, but reflexive. The problem is being exacerbated, but I don't want to use passive voice. Most words in English that are synonymous with "worsen" imply getting weaker or smaller, but I want to say that the crisis grows stronger (yet worse at the same time).
