This is a short, linear memoir, recounting the author's teenage years and the onset and progression of her OCD during this time. I have been diligently looking for books about OCD that center compulsions other than/beyond hygiene compulsions, and I was so grateful for Bailey's focus on "invisible" mental compulsions. This covers a lot of really helpful territory for OCD nonfiction - giving insight into mental compulsions, "just right" obsessions, and magical thinking, in particular. I appreciated the window Bailey gives into the workings of her mind and how visceral her thoughts feel. It's an incredibly vulnerable approach to her own story and emphasizes the ways in which OCD can be invisible to others until its severity impacts a person's day-to-day life. Her experiences in various inpatient and outpatient treatment programs also underscore just how misunderstood OCD often is, how challenging it can be for people to get an appropriate diagnosis and CBT, and how often people with OCD end up lumped into talk therapy treatments for generalized anxiety (which is not typically recommended for OCD treatment, for reasons Bailey explicitly evidences in her own account). This is written while she's still fairly young, so it isn't far-reaching, but it's a first-person account I'm grateful for (and wish I had had when I was younger, frankly).
