Don't quit!!! The more you let your stutter scare you out of things the worse off you'll be. I know it's very scary, but please don't quit. Please instead try breaking up the words in the sentence, even if it may make you sound a bit robotic. Don't be afraid to take pauses or to stop your sentence and start again. Practice a rhythm of saying the sentence that is easier for you to get through. Have a small mirror with you to look into when you speak (as it has helped me). If you stutter it's totally fine too. Do what you gotta do for you! You got this
