I recently started a new job because I wanted to better myself for my son’s future. Well as soon as I started, a guy in my department left, and I was given his work. I was not trained properly and I don’t know what I’m doing. I’m panicking every day before work, and the weekends aren’t enjoyable to me because I just think of work on Monday. I am physically and mentally sick over it. I told my boss about my mental health, but I’m worried I’ll get fired. I just can’t continue to do this anymore. I feel like I’m going insane.
