Edit 20.10.2021:

I sent Margot Wood, the author of the book, an email about this and she apologized and promised to edit or cut the line in future printings.

She said her intention wasn't to invalidate self-diagnosed people, but to call out the people who use mental illnesses like they're adjectives (e.g. "I'm a little OCD" or "She's so bipolar"). However, she recognized that this didn't come across clearly and apologized.

She also explained this here.

Now I finally feel comfortable giving "Fresh" a five star rating, because aside from that, I really loved it! It's a super funny, diverse and emotional new adult Emma retelling, and I highly recommend it!

Orginal review:

I loved this book. I really did. It was funny, it was diverse, it was the perfect new adult book. It made me laugh and it even made me cry. So why don't I give 5 stars?

Because of this:

"I have ADHD, and not in the casual, problematic way people like to self-diagnose."

No. Just no. Self-diagnosis is valid, and for a lot of (especially marginalized) people it's the only way to get a diagnosis at all.

To quote @livedexperiencecounsellor on Instagram:
"Self-diagnosis is not seeing something on the internet and diagnosing yourself because you can relate.⁣ Self-diagnosis is knowing you’re different and spending countless months and years researching, learning and doubting before even making a decision.⁣ If you are against self-diagnosing then it means you believe neurodiverse people need permission from neurotypical people to talk about their own lived experience and identity.⁣ That’s called ableism.⁣"

Shaming people for not being able to get a professional diagnosis is not okay. This comment was just hurtful and unnecessary, and it's the reason I don't recommend this book even though I loved almost everything else about it.
