Yeah i think when I'm in the car for example I know no one can hear me so I don't even think about it. My anxiety triggers my stutter which ends up having a snowball effect. But even in times of no stress I have stuttered or had a mental block.. It really sucks I feel like I'm being held back by it and can't grow as a person, I get a pit in my stomach when I'm trying to talk to someone and can't get the damn words out and end up looking frustrated and twitchy ugh... I work the only job i could find thats the least sociable but it's killing my lower back
