If you can be honest with people before you engage in a conversation or when it starts to come up. Not saying it’ll prevent stuttering but acknowledging the agonizing steeling from it lessen the stress. Of course I’m not sure how some people will react because even at my age there’s still an asshole or two out there. There’s a National Stuttering Association I was apart of and looking at rejoining you can look into that. It’s comforting knowing you’re not that only one going through the same feelings.
