Me too, but instead of language fluency I tended to speak in an odd pedantic manner. (I write this way, too, don't I? LOL) I think all teens experience these difficulties.

I work as an engineer. Sometimes I get into slump of low confidence, and I'm afraid to finalize a design / circuit / program. So I'll keep simulating it with different tools and refining it. Thankfully there are deadlines I have to meet; otherwise I might never commit to having it go into production.

We call this "analysis paralysis."

My impression is that you're stuck inside your own head with something similar. Like another poster wrote, "Just do it," which I'd translate as "set aside the analysis and begin taking action to connect to society."
