Is learning to work in data entry a good idea for someone who's socially anxious and bad at math?

My sibling recommended I learn excel and do it, but I want some opinions from others that have done it if its worth getting into? The only thing I see holding me back is my inability to talk to strangers (as in I might die from a mental breakdown if I have to deal with clients/customers who want to bust balls) and my math skills at a basic arithmetic level (add subtract multiply divide, it doesn't get any better than that). Otherwise, I am gonna have to lock in to finding another warehouse job before my funds totally run out.
