You’re not the only one. I realized a couple of years ago when I got my first job working at Burger King - I had to speak on the intercom for the drive thru. For weeks at a time I could speak so confident, fluently and without any nervousness about my stutter happening then came my “bad” stutter days. Since then I can literally map out what months I’ll have those “bad” stutter days. I thought I was the only one who experienced bad stutter days
