Just some questions.
What happens to those who provide care and support, afterwards?
Are they given adequate support and care themselves?
How long would it take for a counsellor or psychologist to, in a way, forget a patient they have treated frequently over several months? Do you think they still think about patients even after they stop treating them for awhile?
Surely they would maintain a professional distance, no matter how invested they are, do you think they can be emotionally attached to their patient even though it should not be the case? and in a way that they may be irrevocably altered should something happen?
I think they may feel a sense of failure, or guilt over what they may have missed, or may have done wrong, I suppose as anyone who knew the person would, even if they were told that it was not their fault.
