Long story short, I stayed at my old job for 3 years and in the beginning I absolutely loved it. Towards the last year though a lot of things started to change like management and overall policies and practice which made the workplace extremely toxic so I decided to leave. Now I’m starting a new job and I just feel so overwhelmed with everything and it feels so unfamiliar. My coworkers are nice and reassuring but every time right before I go in I just have second thoughts and I wonder if I should just go back to my old job.
