It can be nerve wracking, but it can also be worth it and possibly liberating. I've played World of Warcraft for a long time, and it took me 2 years in my guild before I could build up the courage to speak on Vent even. It definitely helped becoming a part of a community where I felt safe to do that. I pretty quickly became a raid leader(in that game, raids are content with 10+ players) and have done that for many years now and at a fairly high level at times. Heck I stream on Twitch somewhat often too. If it wasn't for that game, I doubt I would have ever had the courage to start streaming at all, or even do a lot of the things I do out of game. Using a game or a streaming platform as a way to build your confidence up can be huge in terms of helping yourself push through the mental blocks that come along with stuttering. I'm 36, and have stuttered for 33 years, and that has probably been the single greatest thing that has helped my stuttering go from debilitating to something I can manage at least. Now it's not all sunshine and rainbows, obviously, but putting yourself into a comfortable situation with people you know and trust and building from that can go a long way, and it makes easier to just push away/block/whatever anyone who wants to speak down to you about stuttering or anything like that. So I would probably suggest playing a game with at least someone else you know and streaming then, so you have a friend to fall back on and to focus more on that than just your audience on Twitch.
