Struggling to Explain Selective Mutism

But i do want to add on, There's things that bug me of course. Like the fact that I'm unable to explain selective mutism to someone else, It's hard to put those things into words??? Because how do i tell someone that is interested with being friends that in certain situations I'll actually stop talking, They've found it odd everytime and corrected me to "just talk" like it's not that easy! I'm anxious. It's like that, Or it plays out with them infantilizing me as if we're both not in college.
