This card really gave me official credibility for leaving placements earlier as specified on my card. Without it, I would have to answer many questions and face some criticism. This card protected my interests, and allowed me to leave earlier without having to explain my full medical history to various staff, thus protecting my boundaries. There was a period of time before receiving my card that I had to explain everything to consultants and tutors, and the response was far more negative. The card was very, very useful
