Last month I presented online in front of 200+ people. I was asked to cover for my manager in an all-hands meeting in front of the entire company. I had a choice. I could have easily said that I don't have the time. But I just won't let it get in front of my opportunities or my beliefs. (btw it wasn't that I wanted to show off, I believed that it is an important topic and I also highly respected the person who asked me to help him by covering in). I think that what led me to be able to and to want to speak my mind is a matter of mindset. My stuttering was pretty hard in high-school. I had so much to say, but I just never raised my hand or pretended I didn't know the answers. Then in 11th grade I just saw how fake people in my class were and questioned why do I even want to make a good impression on them. I just stopped caring for them. I wanted to be my genuine self and find the 1% of the people who have a similar worldview and I would actually like to hang out with. And I could only find them if I spoke my mind. Now I'm 30 and I've been into all kinds of social situations and probably made myself look like a fool in a lot of them. Some people even see it as a strength, though I find it especially annoying when someone gives me credit for just speaking and telling me that "I'm brave". I just have to adapt and work around my weakness and find my strengths. I listen more than I speak - and people tell me that I've very approachable. I try to speak at the right moment - my manager told me that I have weight in my words. But this generally doesn't have to do with stuttering at all - it's just abilities I've gained working. And with time I just gain more confidence. There are still some bad moments, but i just generally try for it not to get in my way. There's a reason why you were invited to speak even with your stutter. I think that's just another opportunity in life. It may not be the right opportunity - this job may just not be worth it. If the colleagues seem annoyed it may be that they just don't care about this job (though it's very likely that you are overthinking it - people mostly think about themselves :D). But in the future other situations will come. It's your decision whether you see them as something to escape from (and go into a negative feedback loop) or view them as practice opportunities.
