Get a playlist of all songs you like, get the lyrics and sing them fully as many times as possible, go for walks to malls and tell people you're doing a social experiment on interacting as a stutterer, most people who have time would interact with you normally, be as social as you like but don't avoid speaking, also learn as many new skills as possible, all this are things I did that reduced my stuttering though some contexts are different because I live in a third world country, the idea is just to stop your mind from being speech avoidant.
