I will be a new case manager in a mental hospital forensic unit

I will be starting a new job as a case manager at an inpatient facility in its forensic unit. I've had experience with care coordination with mental health and drug addiction but they were not felonies. Now I will be working with clients facing all types of felonys and are deemed incompetent for court. it's both exciting for the experience but makes me nervous working with this violent type of population. Any good advice or others with insight from experience?
