@chansdimpledsmile Bro you're so bad you should js quit lmao (JUST KIDDING JUST KIDDING)
IN all seriousness, whatever you're going through to make you think otherwise about updating, take a second to look back over the book in whole, question why did you make that boo? Are you too far in to leave? Is it your absolute passion to write? If you don't find it enjoyable then I see no reason to continue on with the agony lingering over, you as you stress on updating. However, If you are having a simple writer's block then review the book and see any openings or new tunnels of thought to use as leverage. If there aren't any new pathways coming to thought, then leave it be until one does.
Regardless, you're an amazing writer and have so much potential! Many people have doubts about their writing but you should do it for fun, not because you feel like you should force yourself to, (Unless its some type of personal thing or coping mechanism of some sort) You got this and I hope you gain your motivation to update your book!
