Do you think people understand the "iceberg" of stuttering?

Do you think people understand the "iceberg" of stuttering? I just texted someone from a group of people I thought were my friends, but stopped talking to me this year. I told the person how I felt about my stuttering and social anxiety and that why they stopped inviting me to hang out with them. She got mad at me, so I guess some people just don't understand. I guess I shouldn't want to be their friends anyways. Some people just don't understand the "iceberg." Has this happened to anyone else?
