Would you have transitioned if u didn't know other trans people existed?

I was thinking about when was the first time I had feelings of not being the right gender and it was around 12 or 13. And that got me thinking did I know trans people existed then? And Im pretty sure I didn't.

But since I didn't know what trans people were I didn't think of any actions I could take to transition because I didn't even know what that was. Like the concept that I could do this and it's possible didn't even exist in my head.

So just out of curiosity when did you first experience gender incongruence and when did you discover you weren't alone in that? Bonus points if you made any changes before u did
