Artemis, I am so sorry for your loss.
I have written a finished book and a half finished one. I am a member of Jericho Writers and find them extremely helpful . They publish a lot of articles about writing and you can ask them questions about any problems you have. I actually got a phone call from their team the other day and told her about my finished book, and the problem that I had in stopping my repeated editing and adjusting... she said it is because I just want it to be perfect but I will never find it perfect... just get it published!
I can recommend joining JW. It costs about £30 a month if you pay monthly. All the best with your writing!
