I had the same thoughts as you (age 32, stuttering since 3) - this past fall I was in a job that involved many daily calls to tax clients and internal revenue service (IRS). im awful on the phone - blocks, pauses, repetition, anxiety. **i felt like crap because everyone in the nearby cubicles could hear me stutter and i knew i spoke poorly on the phone.** a few times IRS agents hung up on me. after every bad call id go eat junk from the snack machine. i put on 7 lbs in 4 months. i hated this job. i got fired maybe because of my speech. im in a better job now with way less phone interaction and im happier. keep your head up. you're making great contributions to the world - it just takes more time to get your communication across. thats all.
