How do you “walk back” over-sharing with a group about trauma?

I (31F) moved to a new state and joined a book club/activity group 6 months ago. I accidentally over-shared on traumas from my childhood due to nerves early on, a couple meetings in, but I regret sharing those things in a group setting and don’t want to have a reputation as “that person with the bad childhood” who likes to talk about it.

I have since stopped talking about it or bringing it up, but people I am not super close to in the group will bring it up to me occasionally.

Any advice on changing my reputation? I am generally well-liked, but definitely sense this reputation due to questions people ask me about my family.

TLDR: I was “that over-sharer” due to nerves in a group setting. Is there anyway to recover from that?
