I know it sucks, but really you need to try to calm down the aggression lovely. Definitely ask for feedback as it will help. Do you research into the company before you go for interview? What about college? Could you think about going back or maybe doing an OU course or similar?
For the record though - it's a child WITH autism, never "an autism child"... I have 1 child and 1 husband with diagnosed ASD and one who is being assessed... and also that's one of my areas of expertise when I was teaching (Autism and Emotional and Behavioural Difficulties in teenagers in case you were interested )
