not looking for go ask alice

[Destene]

i am looking for a book that IS NOT go ask Alice but very extremely similar but came out between 2000s and 2010s. its about a girl who had a loving family but she became addicted to drugs and she writes about it in her diary. her family published the book and through out it are pictures she drew in her diary. the name megan keeps coming to mind but that may have nothing to do with the book, i also believe the cover is white and a girl is on the front.

Destene, please put genre and plot details in your topic header. "No looking for X book" is not sufficient. Many people won't know what that book is about.
