I Am Consistently Anxious

I dread going on duty everyday. I am afraid of handling unstable patients. I know I should get a grip on myself after all, I’m a licensed nurse. I know it’s too late but I’m thinking I am not cut for this type of job. I want to quit but I am not supposed to. Maybe I really do not even want to. I’m just having a really hard time right now. I am still not used to the flow of things. And I’m uncertain if I ever will.
