So I recently got myself a job after being unemployed for 2 years and it's been so good and I've loved every minute of it. However, they said that they want me to work on the till from now on as well as what I'm doing. This is something that makes me really anxious. I have some "trauma" from a job I had 5 years ago on the till. It really affected my mental health and I used to have a panic attack every day before work and would be feeling so anxious and scared throughout the whole day. So the thought of returning to that scares me. 

The reason I applied for my current job is because I didn't have to be on the till and serve customers. But now because they feel like my job role doesn't involve enough work, they want me to do this as well. Because some days, there's not much work for me to do so they're just paying me to stand. I'm not sure what to do. I don't want to even attend work tomorrow. And I'm freaking out so much
