I’m in college for acting. Ive been in some musicals and multiple short films. It is possible, it just takes a lot of practice and patience with yourself. Don’t let people tell you it’s not possible cos it is. Emily Blunt has a stutter, Marilyn Monroe had a stutter, James Earl Jones has a stutter!! You just have to learn techniques to work through it. If you haven’t looked into speech therapy it has worked wonders for me with my fluency.
