The title basically says it all. I'm fine with talking with people if I'm only with one person at a time. With fine I at least mean, that I don't completely shut down. When I'm in groups, even if it's just 3 people, I feel like shutting down. They talk and I never interject. I just sit there, wait for time to pass or just leave. It's so weird, I can go from talking normally with a person to basically being a mute, once another person joins. And I haven't made a single ounce of progress in that area throughout the years.
