I'm eleven. Ok, so maybe you think that this book is for teens. I'm a lot more mature than you think. That's what I want to say first. So I have been struggling with anxiety and I have been self-harming because I ask the question WHY WHY was the world created WHY did the big bang have to happen WHY did god put me here WHY did something (Whatever it was) create the earth WHY do I have to be here So, maybe this book didn't stop me self-harming, but it helped. A lot. I think it can help other people to. Its incredibly funny, but it really helps you. Seriously, it explains A-Z of why we think about the things, and a lot of other stuff. Please, if you need help, READ THIS.
