Burned out

Hey everyone, I'm an RD who has been one for 4 years. I am working in a psychiatric hospital which deals mainly with substance abuse and mood disorders. I've gotten to the point where I have anxiety going into work because I dislike the job so much. However, the flip side is I've lost all my clinical knowledge because it wasn't pertinent for the job so I feel dumbed down.

Has anyone ever stopped being an RD and went into a different field entirely? If so, what? I'm not sure I want to do this anymore and I'm at a loss as to what else I could possibly do with my degree.

thanks!
