How can I get over people talking bad about me and my appearance at work? I need this job

Hi there, I’m the guy people like to pick on. I just am an easy target I have severe alopecia in high school and always covered up. People picked on me on other things like how my face looks and how I talk. A guy that was in my high school told everyone that I have alopecia and now they mock me with this and it’s brutal. I can’t take it anymore. I need this job though. I had a hard time finding one.
