A problem with using ChatGPT

I was making a story using Chat GPT, and I find that it says conversation too long, start a new one.

And I am worried, and I had to start over, and asking chatgpt, to create a new one, but they wont remember a thing on a chat I called which contains the story: Fantasy and Modernity.

idk what to do any more.

So I’m saying please do something, it took me 5 months approx
