Where I live there are plenty of people with various disadvantages: mental disorders, speech deficiencies, physical handicaps, orphans who live in shelters, homosexuals, colorblindness, whatever. I know I personally wouldn’t care if someone I knew had selective mutism. But we try to accept them all. I’m sorry you don’t live in a similar society. However, I do know that I have a friend whose brother is in college and she says it is AMAZING. Apparently everyone there is very accepting and create a community sort of relationship. It’s better than high school, so know that’s coming.

Tip: I used to be deathly shy as well. But as I overcame my fear and started to accumulate more friends I realized that shy people were often ostracized not because other people didn’t like them. It’s because they’re so self conscious they don’t try to join them. Don’t even worry for a second if they think you’re weird. Even if they do at first often times they will come to accept you and like you for your quirks.
