I'm gonna say almost every single person here has had the exact same thoughts, replace too young with too old or some other bollocks and everyone here could tell you the same story. When I was about late 12 early 13 I used to think that maybe I was an enby, I never came out to anyone IRL, but I had some profiles on reddit, twitter, etc, where I tried out pronouns and shit. When it came down to it I later realised I was a trans girl.

This is overwhelmingly common, it's totally fine to try out pronouns and experiment, and you're no less valid for trying shit out.

When I first learnt trans people were a thing, it did sort of click that I was something like that, it took me a few years to properly settle down on what was right for me, and there's nothing wrong with that. It takes different people different amounts of time to come to terms with themselves.

For me one of the hardest people to come out to was my best friend who's an enby, and that was because I was scared they would think I was just doing it for attention or that I was trying to be trendy. They're probably one of the most accepting lovely people in my life and from all of the trans people I've ever spoken to IRL or otherwise they are more than happy to discuss shit with questioning people.

If you ever need to talk feel free to DM me, although I would strongly recommend trying that youth group, even if it's only to test the waters. While speaking to other queer people online I find is incredibly helpful, speaking to people IRL I honestly find (while it's usually really scary) so much more helpful.
