ghoulure's journey

I recently started my first job in food service, and it's been quite a challenging experience. I’ve been working there for just over a month, but I’ve faced some difficulties adjusting, especially since I had been living in an isolated country for several years prior. This has made my transition into the workforce feel like a massive cultural shock. Unfortunately, my manager has cut my hours significantly because they said I was too slow and timid. I understand that as a new employee, I’m not a priority compared to those who have been there longer, but the inconsistency in my schedule is making it hard for me to improve my skills. I often find myself overthinking during my shifts, which only slows me down further. I feel a lot of pressure to perform well quickly, and it's been weighing on me. I worry about what my coworkers think of me and whether I can change their perceptions. I know I just need to keep trying, but I’m starting to feel like I might be stuck in this situation without a way out. Has anyone else experienced something similar? I would really appreciate any advice or reassurance.
