anxiety about going to work

Hey ladies, I get super severe anxiety about going to work to the point where I'm having anxiety attacks days before my shift and will cry the whole day before. I'm a casual and only work weekends so I spend the whole week anxious. I've never had anxiety about a job before but I can't quit because I make great money for my age. I have the opportunity to go for an interview for the same job somewhere else (I work behind a bar at an rsl but will possibly be moving to a leagues club) but I'm worried I'll still have the anxiety. What do I do? I want to see someone about it but I just don't have time or a way there. Do you have any tips on making it stop or if the other job will be different?
