HELP please, I wrote a story with the help of AI and now I can’t pick what’s mine and what’s AI

Hello everyone, first of all I have to apologize for my English it is not my first language.<br>I wrote a fantasy novel and then I decided to use AI to get some Ideas, and everything was fine so far, but I don’t know what happened, I might have clicked on the wrong button, but all of a sudden the AI added a piece of writing in the story, a piece that I didn’t write, it was a scene of description of one of the characters, background and personality. It was beautifully written, and I was so impressed with it, and then I asked myself why can’t I write like this? I mean I wrote the whole novel, and yet I don’t like my writing. So I continued with the AI, asking for more help and more ideas. The problem is that after a while, I realized that I can’t figure out anymore what part of the story was written by me and what was written by the AI, it was like as if the novel was not mine anymore, and I couldn’t tell what was my own ideas or not. I was spending more time thinking about that rather than the story itself, and it was really confusing, and honestly I was a bit angry and I still am, because this has never happened to me before, I have always been able to recognize my own writing and recognize who that I am, and now I feel that I can’t really. I feel like my own identity is being threatened, and I just don’t know what to do. I feel like a failure and a liar as well, because I am worried what others might think of the story. I have always dreamed of becoming a writer, but now I am starting to question this dream, because I don’t know if what I am writing really comes from me or not. I am worried what if I become a real writer, no one will be able to tell if my stories are mine or not. <br>So now I really don’t know what to do with my story, I have two options, either I change the whole thing and write it again from scratch, or I leave it the way it is. The thing is that even if I decide to write it again, I don’t know if I can really write it again without any help from AI, and what if it’s not good enough? No one might like it anymore, but on the other hand, I really want to prove to myself that I can write a story on my own.<br>And I am not really sure how to play it, do I tell people about the AI, or do I just keep it in secret? I am scared of how people might react when they find out, I don’t want to be accused of plagiarism or anything. If I don’t tell anyone, then I will be a liar as well, even if I do tell people, what if they stop reading my story. I know that I probably sound over sensitive about this, but this is my whole dream about being a writer, and now I feel like everything is ruined.<br>I hope someone might have some advice, I really would love some. Thank you<br>Tldr: I wrote a story and asked AI for some ideas, but then I couldn’t figure out anymore what was my own writing and what was the AI’s. Now I am questioning my whole dream of becoming a writer.
