My problem is talking to myself too much.

I have a problem with talking to myself excessively to the point where I speak out loud. Even when I’m just thinking, I do it in the form of a conversation or a debate. It has become bothersome, and I can no longer control it; I find myself sitting there debating scenarios or things that don't even exist. If anyone has had a similar experience and found a solution, I would really appreciate the help.
