There are VNs that are generic life sim sandboxes where you play a normal person. They're mostly porn though.

Your recent posts remind me of some forgotten internet lingo from the LiveJournal era - e/n, short for everything/nothing, as in posts that were incredibly meaningful to the poster but not to anyone else.

Your story might be better received in a community like offmychest or mildlyinteresting or a confession one - this isn't really the audience for these.
