I think my stutter is a confidence problem

I think my stutter is a confidence problem I posted on here before but I have a different question ab my stutter. My stutter is only usually the first word of the sentence. Everything after this is fine. So now I am thinking that is more of an anxiety problem. When I’m drunk I don’t usually stutter because you don’t think about it you just say so that kind of convinced me that it is anxiety. Anyone have ways to stop thinking about talking and just to say the word.
