I just started to stutter, is there a way of stopping it from getting worse?

I just started to stutter, is there a way of stopping it from getting worse? Lately, I’ve been isolating myself from everyone. I usually only talk to myself when I’m showering or when I’m bored. I’ve started to stutter even when I’m talking alone; it happens just by imagining that other people are listening to me. Is there a way to stop it from getting worse?
