It’s weird as hell....

It’s weird as hell.... So I work at an office where I just transfer people calls to different offices it’s not that bad of a job it’s really simple I realized recently that I’m not really stuttering when talking on the phone with others at work and I mostly stutter on the phone in general I mean I do k the reason why because In generally when I’m relaxed and less anxious I do not stutter at all. I felt confident and felt like I knew my shit on what I was telling him on the phone And the time when I was in class I was nervous and anxious and my chest and neck started to tighten up and my heart was beating really fast and started blocking on every other word Do anyone experience this? Can anyone relate?
