I am similar. I struggle with introductions and I struggle when speaking in front of groups. I self advertise, it is all I can do. “Hi, I am … …. … Rrr ….. …… geez …. Rokkitt. I have a stutter and apparently today it is severe (chuckle to put people at ease and purposefully pause for my own composure). I work at… (where relevant I will try to shortcut what is next e.g. “I have the same certs as X.” And add a sentence to make it my own” I feel this helps me a lot. I explain what is going on. I show I am comfortable acknowledging it. I feel it puts myself and others at ease. I try not avoid things. That said, I was recently asked to present to 100 people at a company event and I told my manager it ain’t happening. Instead we agreed that my objective is more talking events with smaller groups of people so I am more confident in these situations. I felt this was a good compromise. You said something like it is pathetic to get nervous while talking at 30. I asked someone to present their work in front of 4 people as I thought it was really interesting. They didn’t have a stutter but they did have a panic attack a few minutes before and skipped the call. Anxiety is a real thing that affects a lot of people. I am really proud of myself when I get out of bed, get into work and start presenting despite my difficulties. I have a lot to contribute and overcoming the struggle and getting things done is something we should all be proud of, regardless of how fluently it went. I wish you all the best. I hope your event goes well.
