selective mutism/anxiety/social anxiety

Selective mutism is a major social anxiety disorder most websites show that only children have it but that isn't true adults and teenagers can have selective mutism as well (I have had it my whole life) and I am only recently getting proper treatment for it but treatment is really difficult and slow for selective mutism if you would like to know more about selective mutism I will post my youtube video that i have made which explains more about selective mutism.
