Is my stutter normal?

Is my stutter normal? My throat just randomly closes to the point only a tiny amount of air comes out (you can hear it) but no sound. I believe repetition of a phrase helps but not always. I used to work at a restaurant and I had to answer the phone (my NIGHTMARE!) a lot. About a week in and I was FLAWLESS with what I had to say and talking about the food. BUT to this day I stutter with my name (first and last) but that might be just me having an issue with beginning sentences. I don’t generally get hung on a word “w-w-water” style but my throat just closes. I have a ton of anxiety so that definitely doesn’t help. Any thoughts?
