Started a new job.

Two weeks ago I started a new job and every single night I can’t leave my mind at work. When I’m trying to sleep I’ll wake up panicked that I didn’t do something and that I’m going to get in trouble or I’ll have it’s not really a dreams is more of a lucid dream or a hallucination between being asleep and being awake about setting up for different in office procedures (I’m a medical assistant.) I’ve never had a job like this before. Has anyone else ever had this experience? I’m exhausted because I can’t get a real good sleep.
