I don’t have what you described, so I might not be the best one to help you with, but I will certainly try! What I do to get over my stutter (which is medium-sometimes severe) is I talk to myself and intentionally stutter so I know what it sounds like when it’s bad. That way, when it gets severe I can think “at least I know it could be worse” (side note, my stutter has gotten so bad as to be extreme for about a week long period of time, so I truly do know what it feels like) This helps me when I have to present something or talk to new people, because I know that I will be able to communicate effectively, how the other people react is their problem. I try to explain to people that I have a natural stutter impediment when they start to react to it more. From then on I ignore any frustrated looks I get from them if the conversation needs to happen. (Like if it’s a customer, talking to a co worker about something important etc.) if it’s not a vital conversation then the people who complain about my stutter don’t normally talk to me anyway. So the problem takes care of itself. Again, I have a stutter, not a slur. I don’t know if this has helped or hurt you at all, and I’m sorry if it doesn’t help, but hopefully it has though. As for your job, I can’t really say anything there. If you do as good a job with your slur as people who speak fluent, then it’s them who struggle, not you. But if you think that you need time to bolster your mental defenses, then you do what you think is best. I wish you the best of luck, and again, sorry if this hasn’t helped. Heart goes with ya though!
