I have social and anxiety and stutter and am engineer and I deal with it every day if my life. My stutter isn’t related to repeating the same word over and over again. I get speech blocks when starting sentences and mid sentences where I can’t talk. So for example if someone holds the door for me at work, sometimes I can’t say thank you right away. It may take a second or two before I’m able to say thank you. Starting a sentence without stuttering is really difficult for me depending on the sentence, but I’ve been able to try to mask my stuttering with filler words and pauses throughout college and my professional career
