I am not sure if I read the same book as others. Why did I hate it so much?

There is some strong character development, I have to give this book that one. 

There was an attempt at writing a great book about mental health. Attempt. It almost felt like there was this toxic positivity. I did not enjoy this at all and I remember being so bored with this book. Maybe this just wasn't my cup of tea. Maybe this was just a bad book. I think this mental health awareness that was going on in this book was just not meant for everyone. I did not understand how anyone could find comfort in this or find it relatable. I'm sure it helps some people or others like this, just.. I find it way too overhyped and I fell asleep twice reading this. Maybe not my cup of tea. Now, how do I unread this?
