Has it ever happened to you too?

It happened to me again. I was in a gathering with three girls. As a person with social anxiety, I strived to talk as much as I could. It was all fine at the beginning because we had the equal amount to talk. Until one of them left, the other two girls started ignoring me. I asked the same thing thrice. At the first time I thought I was just too quiet so they couldn't hear me, yet at the second time they still couldn't hear me, and at the third time, I finally realized that they have been speaking louder and louder to cover my voice. I stopped making a sound and walked behind them. I didn't get it, I tried, it seemed good, but then I became air again like what I've always been.
