I had a friend a few years ago who did a similar thing, only she declared she’d taken an overdose in the middle of Safeway and then ran off. A couple of hours we found her and took her to A&E. We waited the best part of 5 hours for her to be seen and treated. Her ex went in with her, who was also a nurse in the department, and once we were on our way out dropped HUGE hints that she couldn’t have taken more than 4 pills. There is no doubt that this was attention seeking – she did it frequently, as well as cutting herself, but never seriously. It never seemed to enter her head that we had been very worried about her, nor did it occur to her to thank us for sticking around A&E for hours on end and leaving at god knows what time.
