What jobs can I get where I don't have to talk much?

What jobs can I get where I don't have to talk much? I currently work as a data entry clerk for an appliance parts store. I block a lot when I answer the phone and in the last couple of times working I have been laughed at. I know it probably isn't out of spite but nontheless whenever anybody laughs it breaks me on the inside. Words can never explain the full extend of pain this condition causes me. I have gone into the bathroom at work sobbing wishing I could go home. I have to go back tomorrow and I am not looking forward to it at ALL. Plus my manager is going to be in the back office where I work and he is going to hear me choke and stammer on the phone. I feel like he judges me for it and I fear he will say something about it and I will get interrogated. So, I am looking at jobs I could possibly get that would not involve phones or having to talk to others. I've come up with housekeeper, mailman, etc. are there any others?
