I understand you. I have struggled with stuttering my whole life, and my ambitions have also driven me to filmmaking process. Unfortunately, as my projects grew larger and I had to manage a dozen or so people under stress, my stuttering was getting out of hand. It lasted a few months, it ended with a severe depression, which I still can't overcome after 6 years. Nightmare. Better to suppress your ambitions. Or spend a few years on truly effective speech therapy to remove stuttering from your life.
