I've been researching a little about jobs that require little interaction with people. Your local community college has lots of programs that might be of interest. Speak with a community college counselor and they might be able to suggest some degrees. Most require 1-2 years training.
Try to find a career that you can have little human contact. Don't spend your time studying to become a teacher where you have to be confined 8 hrs a day to one room with students and have close interaction with them. In the long run, you'll only end up quitting due to stress.
We need secure jobs we can live comfortably financially not just barely making it.
