Fictional book about a depressed writer who loses his wife and battles against depression, struggling to finish his book.

Been trying to remember what the title of this book is for ages. One of my favorite reads of all time but it's been so long. Basically from what I can remember, there is an author who loses his wife in I think a car crash of some sorts or some other way. He struggles throughout the entire book with alcohol addiction and can't ever finish the book. Finally at the end, he finds peace, finishing his book and battling his suicidal thoughts successfully. Hopefully even with just this vague description someone can help me out. Thanks in advance! I read it back in 2014 i believe.
