I see. Then again, perhaps they hadn't come across a student with such a disorder. When I was at my previous sixth form - a prestigious grammar school - they were rather ignorant to my academic struggles, but were adept when it came to aiding me with the more minor mental health side of things...to an extent.
I started to self harm from as far back as year 8 and conjured up the courage to confide in a teacher in year 10 when i'd tried to commit suicide. They were completely and utterly useless. They did nothing but inform my parents without telling me first, so I went home and received an interrogation from them.
Things started to reach their peak when I started the grammar school sixth form, which resulted in hospital admission. It turned out I had Aspergers Syndrome, which explained the academic issues. However, the grammar school sixth form were just as useless, as they more or less kicked me out after realising the extent of my mental health problems. Needless to say, I was gutted and it further deteriorated my mental state whilst still in hospital.
Anywho! I'm now in a good comprehensive sixth form who provide astonishly supportive pastoral care. I'm happy where I am even though i've had to settle with somewhere that i'd never have considered previously. I suppose I just don't want a repeat of the grammar school's reaction towards my illness. It's reassuring that your welfare team were so supportive during your psychotic episodes because i've had to deal with some obscure reactions to my psychosis which just makes things worse.
