It's okay , my friend. I know you've done your best and sacrificed so many things to fight your struggles and to get to where you are today , not only that but to get the job you want . If you're happy in your current job , please don't leave. Don't let your stuttering get in the way of your happiness. Most people are understanding and willing to listen even if we think( us stutterers) that they won't because we think they're bothered by our blocks and long silences , but the important is the message, not the way we communicate it. However, you've been chosen for this job because you deserve it and God wanted you to sharp your skills of communication by putting you in situations like this when you have to speak a lot . actually God is helping you finding your way to become free of your fears . that's God Loving you Sending all my support to you . I can relate to all of what you said . if I was in your place , I would be so confused and not knowing what to do , but I'll probably try one more time to see if it works.
