A bit of context:
I suffer from depression, severe anxiety (e.g. panic attacks which tend to span into a psychotic episode at their peak), OCD and I have a diagnosis of Aspergers syndrome. For the past year I have been in a psychiatric unit both formally and informally, but I started a new sixth form in November after my old sixth form abandoned me because of my illness
I'm due to take my psychology AS exam on Monday, but yesterday I had a severe panic attack. I gradually became psychotic where my parents had to call the police for fear of harming myself or my baby sister, who then called an ambulance after I had an asthma attack from hyperventilating. Fortunately things were on the mend by the time the police arrived who helped to calm me down, but i'm terrified of having a panic attack during my exam.
Is there anything that I could tell the exam board or apply for, such as, special consideration if a panic attack of this severity were to recur? Btw, my teachers are aware of my situation and i'll be taking my exam in isolation because of the anxiety issues.
