Some unwarrented advice you dont wanna hear. If you look for the job that you dont need to talk in, you will never see any progression in your speech. I realized this at a young age and went for a job that required me to speak more than I was used to. I truly could not imagine what my life would be if I took a job stocking shelves on the night crew or in the back of a wearhouse somewhere speaking to no one all day. Do youself a favor and dont give up on yourself. You can have any job you want.
