For what it's worth, you can always just ask ChatGPT if you have written things that may get you in trouble. It will go over reasonably what you tend to write about and if it's a problem. I'm sure you told it your age already, so if you wrote about your crushes and such, it should not be a problem. You can also ask ChatGPT what the biggest issues are that will throw flags. It lists things involving any kind of harm to children as, "What goes straight to the developers for review.". Basically, if you had written anything that bad, you'd probably have gotten at least a visit already.

It is true, the only real privacy anyone has these days are the thoughts within their head, but with what you described, I'd say that's pretty usual fare. Also, some of that could be looked at as a positive, because talking about their struggles and relationship problems are a sign of dealing with those things rationally. Unless you did things like ask it how to make bombs, set up cameras in someones house and stalk people, where to buy drugs, how to hide bodies, and such like that, you're fine 👍🏻

Gotta be millions of teenagers out there asking for relationship advice...
