I'm a psych nurse and I carry patients around in my head all the time. I try to leave my patients at work when I go home, but some people I worry about when I'm off - wonder how they're doing and if they're safe. I think about patients who have left - wonder how their home situation is working out, is their new therapist making a difference, are their meds working. And I pray for certain patients too. But I don't talk about them outside of the hospital - it wouldn't be right. Besides that would be breaking confidentiality laws. Therapists are bound by those same laws - they shouldn't be talking about their patients either.
