What career is right for me?

Let me start off by telling a bit about myself. I have severe verbal apraxia: literally every word I say is mispronounced. I've had Speech therapy from preschool till 9th grade with no avail. Till recently, my dream job was to be an auditor for the IRS; however, I recently took physics, a highly group based cl, and realized that my speech impediment is too severe for a job that relies so heavily on speech skills. Which leads to my question: what career is right for me? My best subject is history; my favorite subject is math. What job requires minimal communication skills?
