Work Anxiety

So I’ve never really worked long hours, I have two jobs now because the first one doesn’t work me enough but it’s not her fault. I worked at the Medical Office as a Laser Technician for a couple of months and then just recently introduced a “part time” job at a traveling gas station. I wasn’t feeling the best about the decision before I took the job and even had a mini anxiety attack but I have no idea why. I need the money so I took it. Tomorrow is my second real day and I can’t sleep because of my anxiety about it and I feel nauseous. It’s 2:21am but I can’t seem to sleep.

It’s “part time” however I’m working 8-9 hour shifts and working +30 hours a week. I’ve already been scheduled so I know. Tomorrow is an 8hr but I just feel so anxious. I need the money to pay some small things but it’s just giving me sooo much anxiety right now and I’m not sure how to handle this and I honestly just needed to get this said to someone, somewhere.
