It sounds like you're not comfortable with your job, if it's making you that anxious. I remember having a job many years ago which I felt trapped in (for reasons I won't go into here). As a result I started drinking to mask those feelings. It's better to address the underlying reason. Some people are comfortable working with people (receptionists, teachers, emergency workers, salespeople, doctors, etc.), whereas some people are more comfortable with "things" (tradies, engineers, scientists, IT , mathematicians, etc.). Just from the few comments you made, it sounds like you may fall into the 2nd category. There's no such thing as job A is better than job B; it's what suits you best.
