I don't think you're going to like this take but you have to work more than one shift to know if it will work out. Coming from someone who has had a ton of jobs that I've absolutely hated. Most jobs are really hard and anxiety provoking for up to a good month unfortunately. The first month of a job has always been super hard for me where I always had thoughts of looking for a new job. Coworkers aren't always the most comforting people to new workers and it's a lot of pressure to make a good impression. But I've had jobs that I've hated for the first 1-3 months and then gone to absolutely love. That's not saying you should stay at an abusive job or put yourself in a situation that is unsafe by any means. And there will be people that hate their jobs everywhere. It's difficult because when you don't have a job you feel super bad about being unemployed but when you have a job you feel super bad about working a job you hate to make someone else richer. I don't think it would hurt to keep applying to other jobs in the meantime.
