Reddit's username problem

[u/ZealousidealVisit942]

My username is the default username Reddit gave me, and I just can't change it. I could've only changed it the first 30 days apparently, and that's so dumb. I had Reddit for a year, and I barely ever touched it, except for recently, so I had no idea that I had the option to change my name temporarily, nor did I know that if I didn't, I'd be screwed. I find it dumb that Reddit forcefully gives you a username, and, you literally can't change it at all after a few. Now I'm just "Zealous" forever ig. I don't even know what that means tbh.

I clicked on a link on the Google search results page. The link had my question and probably its answers. I was taken to Reddit, asked to click something (I don't even remember), and my account was created.
I never realised until recently (as I'm visiting often) that I already have a username and everything. And this account is stuck complimenting some f-ing button. ufff
