I also wanted to advise you to keep a log of what you've eaten and when and what has been said to you.Repeating scriptures will help you get through the mental anguish in social settings. Don't quit your job! You have a right to work in a harrassment free environment. You may have to bring it up with your boss.If you feel uncomfortable in brinig this up with your supervisor, write him/her a letter and give it to them out of hours. Try not to get overly timid to discuss the letter because it will be just as difficult for them to talk about it to you as it is for you.Try not to become isolated and seek counseling servces preferably Christian/Catholic.This happened to you for a special reason that we dont know. There are people far worse off than you but God will get you through this so you can in turn help others =)
