You are not alone i have introduction anxiety sometimes i just can’t get my name out spelling it out sometimes helps or just let people know you have a stutter block just recently i made a metal business card stating my name and under my name i wrote i have a stutter block and anxiety when introducing myself and i am going to present that whenever i feel the anxiety and block coming on and there is nothing wrong with that we have to normalize different things like this that make us feel better instead of thinking there’s a magic cure and that is ok hope your doing ok much love
