Leave their work at work and do not take it home, and the
same for personal home problems, they must not let that get in the
their work. Imagine how drained your counsellor would be if she stopped or went home and thought about all of her patients and their situations?? They are taught not to have emotional attachments to their patients, and they don't. If they worried about every little thing, then they would need a Psychologist aswell.
