13 modi di vedere una ragazza grassa

The book was fast to read and well written, so what went wrong?
This book is formed by 13 episodes in which we follow our protagonist through her eyes and a couple more points of view. The short stories follow Elizabeth since she is a teenager and till her adult years and each episode is a spiral of selfhate, spitefulness, bodyshaming and general lack of any hope in life.
The author paints a merciless portrait of a woman obsessed with her weight and that single thought dominates hew whole life. She is not a likable character, the events in her life (both those described and those only mentioned) are all dull or bad or depressing.
I hoped for somethinng completely different when I bought this book. There was no hope, no growth, no improvement or the slightest moment of joy. The author's purpose of showing a raw and mericiless portrait has been successfully achieved, but this kind of book isn't for me.
