Hi. I have in fact done this type of work and realise how pressurised it can be at times. Some of the incidents you have to deal with can be very upsetting, and sometimes you ask yourself, 'Could I have done that better'. you can feel so helpless following an incident and ideally there should be a debrief where upsetting incidents can be talked through. I know where I use to work they liked to have their Comms workers to be older, with more life experiences. it sounds to me that something has happened which has upset your daughter. if you know of anyone who your daughter would confide with, I would tell them about your daughters behaviour and see if she would disclose something to them. Best of luck.
