I hate my name, Erzsébet—feels outdated and I can’t shake the negative associations

I absolutely hate my name. It’s Erzsébet, and I feel like it’s so outdated and old-fashioned. I’ve never even met anyone with this name except for some weird anime character, and it doesn’t feel like it fits a modern person at all. It feels like my parents just slapped a bunch of random letters together without thinking about how it would impact me later. Honestly, I can’t even have cute nicknames or usernames because of it. It makes me feel disconnected from everyone else, and to top it off, the only person in history with this name is a serial killer. I just wish I had a name that felt more me, but changing it seems like a hassle because everyone I know would think it’s weird. Has anyone else been stuck with a name they hate, and how did you deal with it?
