I need advice.

Hi, I just started at Target about a month ago. I find myself absolutely resenting going into work and find myself to be entirely miserable even thinking of clocking in. I haven’t experienced this with previous jobs. I work as a fulfillment expert and I’m being scheduled around 30+ hours a week, most shifts being over 7 hours. The pay is pretty much the only reason I am hanging onto the job, considering it’s almost double what I made previously.

I sobbed after my shift today. Does it get better, or is it worth it to find other options? Did anyone else have similar experiences starting?

Extra: (I have worked previously in customer service and none of the customer work bothers me in the slightest. I genuinely have no clue why it makes me so unhappy and anxious.)
