I’ll echo what others are suggesting and say give it a look.

I went undiagnosed for years and really struggled with a number of things. I’d talk over people, interrupt, and finish peoples sentences (to name a few that may resonate with you.) I was consciously aware of what I was doing and frequently battled the urge to do it. I eventually went and got diagnosed …and holy hell what a difference it made. It was no longer urgent to express an idea before it was lost to the “noise.” It wouldn’t hurt to speak with a doctor / specialist about it; you have nothing to lose and potentially a lot to gain.
