Just a rant; honestly, might quit
So, I am pretty young, but I have been working for store 503 for a year and a half now. It will be 2 years in August. I am just graduating from high school next week on Wednesday. I've had so many things go wrong this past year that have made my mental health decline rapidly. I'm not the fastest on register; I can hardly get past 14 IPM most days. I primarily work in Self Check Out. I have had many customers, and I truly do love them, except for a few who have been difficult when asked to show their ID. Getting through each shift is a trial in itself. My CSM knows my current situation and how stressed out I have been. Even the backup CSM and one of the floor supervisors do as well. I have constantly tried to do what I am asked, and I feel miserable, and they quite literally told me I'm unreliable. It's my first job, and I feel like quitting would look terrible, but I can't stay if I'm this miserable either.
