I agree with everything you said. I personally don't have mental anxiety anymore, only strong physical symptoms which I'm working on how to fix. Nobody I meet is bothered by my stutter, but when I specifically try to hit on girls, I can't help but feel that many of them immediately categorize me into the friendzone because I appear shy and nervous, even though I'm really not. I could also be overthinking this and in reality this might not be the case, but who knows.
