Im starting to stutter, is there a way from stopping it from getting worse?

Im starting to stutter, is there a way from stopping it from getting worse? Lately I have been isolating myself from everyone. I usually only talk to my self when I shower or when im bored. Lately I´ve started to stutter even when im talking alone, it happens just by imaging that other people are listening me. Is there a way to stop it from getting worse?
