It's much easier for me to tell somebody else "any job. If you have to talk a lot it's going to help you", but I do have to be at least somewhat sympathetic because I was in the same situation. I worked in the kitchen of a fast food restaurant, which was only really possible because my brother was an assistant manager. Stocking shelves at a retail or food store, or kitchen of fast food is a good option for somebody who stutters. I'm 22 and searching for a post-university job and I still have high levels of anxiety when meeting new people or have an interview. If I had more exposure to "the outside world" like I would have with a speaking-job, I probably would be in a better position anxiety-wise. Just my thoughts, good luck.
