I wanna know why do I tend to feel like I’m losing myself or part of it whenever I share something with ChatGPT in general?

For context, whenever I share something with ChatGPT, it's like I'm giving a piece of myself to it, it mirrors me somehow. But when I delete the app, I lose that part… For example, say you're a good writer and you shared how good you are with ChatGPT, delete the app and you'll never think the same. That's my case.

Is there a reason behind this?
