I wrote a book about everything I thought while stuck in a certain situation I have only partially come out of throughout many years (sort of like Anne Frank, but I don't think I'm as wise). Do you think my book would be able to be received with a good audience?
It doesn't matter how your book is received. What matters is that you write the book of your heart before you die. If this is that book, don't worry about what anyone else thinks and go for it. No matter what anyone else will think, you will know that you wrote your soul onto paper. Or something like that. Good luck!
