Poppy didn't answer right away. Instead, she encouraged Brigitte to breathe. Made her drink some more water. Fixed up some more tea. A good half hour passed that way until she was able to get the young witch to calm enough that she felt like they might be able to make some headway. 

"You've not even completed your OWLs yet," she said. "I won't say it will be easy, but you can still bring your marks up and pass your OWLs with decent enough marks to get into the right courses for your NEWTs. You are not automatically banned from becoming a Healer simply because you have dealt poorly with stress. That you are in here and not in a loo somewhere bleeding is a huge step, no matter what you might want to argue. 

"Tutors and hard work and keeping your focus on your dreams will help. Sometimes the best Healers come from places of darkness, Brigitte," she said, her hand on the girl's shoulder. "Healers who have been through hell and back tend to have a deeper compassion for those in pain. So, you see, your pain can be turned into something good, Brigitte. But you need to want to find that desire to reach your goal."
