Your experiences are very similar to mine! In the past, I've been able to fly under the radar really well by substituting words. Many people have told me that they never noticed unless I told them. My stutter got really bad last year when I started law school due to the intense anxiety and stress of it all. Also, it's not so easy to substitute words because the law has a lot of terms of art that you really can't get around saying, even when you feel the stutter coming on. It's been way more manageable this year now that I know what I'm doing more and feel more comfortable. I do think that an attitude of acceptance is really important. Like you said, it's "part of you," even though you might wish there was some way you can just shut it off. Something that's been really successful for me is by trying to put on an attitude of confidence--as in, if I tell myself that I'm not going to stutter, usually that's been successful. Or when I do stutter a little bit, I remind myself that it's okay and that the person I'm talking to can just deal with the fact that I just stuttered. If I do feel the stutter coming on, it helps to pause for a second and just relax my vocal cord area and let it come out. I know that stuttering isn't entirely psychological, but when you're very conscious and worried about it, especially in a new and uncomfortable situation, it's almost self sabotaging to keep telling yourself that your stuttering is for sure going to be a problem. I know this is easier said than done. I do think that once you're more familiar with the new professional environment, it will be way easier to cope.
