I've had the opposite experience, and in the spirit of being opposite I'm going to break the trend of terse responses and type out a longer one.
I was very quiet as a teenager, always let other people lead the conversation and had trouble opening up to people. Whenever I did speak up with an opinion or idea of my own I would feel like I had broken the flow of the conversation, like my contribution wasn't quite relevant, like people were just waiting for me to finish indulging my ego before carrying on with the real conversation. I would feel separate to, rather than part of, the conversation.
Taking psychedelics (mushrooms and LSD) for the first few times when I was 19 changed my perspective forever. I was tripping with some new friends at I had made that year at university and usually I was exceptionally shy around people I did not know very well. The most amazing thing happened: I started looking at these people as fellow human beings complete with fears and insecurities, ambitions and values, things that I had never noticed before in my single-minded focus on making sure that I wasn't being awkward or weird.
Turns out that everyone is awkward and weird. I started to hear notes of uncertainty and restraint in the way people spoke to each other. I realised that the pauses that I had been interpreting as awkward silences weren't being perceived that way by anyone else, and there was no "real conversation" that I was interrupting when I voiced my own ideas. I felt like it would be OK if I raised this with the group, and they were very receptive. The ones who I had thought of as being more talkative and chatty worried that they talked too much, the ones who were less intellectual worried about sounding stupid, the other quiet ones had the same worries I did. Suddenly it was obvious that these worries were baseless, we all kind of just do our thing and people can make of it what they like.
An example is this post. Maybe most people skip over it. Maybe most of the people who start reading it don't finish. Maybe most readers think it's too long or too personal or irrelevant. It doesn't matter, because the best we can do is just share our experience and that is worthwhile even if occasionally it might expose us to awkwardness.
