Well maybe this is a terrible way to deal with it, BUT I accept that those people have terrible conversation skills and will take a back seat in the conversation. I take a few deep breaths to help me chill out then pretty much just listen. The deep breaths help loosen my vocal cords too. I absolutely hate when people ignore and interrupt me, it really makes speech difficult for me and frustrates me SO MUCH. I know some people do that on purpose to make me stutter.
