My dd (now nearly 13) has always been in mainstream education and was diagnosed with high functioning autism two and a half years ago, although it was clear that she was struggling socially for some time before that, but academically speaking she did well at primary. However, secondary has been a different story. Issues with tummy pain and not wanting to go to school were initially thought to be psychological difficulties, but eventually she became seriously ill, was diagnosed with ulcerative colitis and was hospitalised for two weeks last year while they got it under control.
Though she is now mostly better (she still has low grade symptoms), it has become very difficult to get her to school at all. We did not have a particularly close relationship before her illness but now she has become clingy and dependent on me (not surprising, I know). I have to sit by her beside every morning to make sure she gets up and dressed, and if the slightest thing goes wrong with her morning routine there is a meltdown (she cries like a toddler) and I know I will be lucky if I get into school at all. I am told she barely interacts with her peers at all at school. She has a few friends, but those friendships are often maintained by me. Though she has a phone, she doesn't text or phone people and no-one texts her, and visits by friends are always initiated by me through parents. Though she is, or at least used to be, an avid reader, she has withdrawn into a world of screens much of the time. At school she is escorted to and from every class by an LSA, I think largely to ensure nothing is said to her by other children that might cause a meltdown. When she's at school I'm not sure how often meltdowns happen as I don't know how good the school are at recording them, but her academic achievement is falling now as well, hardly surprising when she is on 60% attendance.
She is not statemented, when she was in initially diagnosed we were told there was no point in applying for one as her academic achievement was too good. Given all her problems, I am now contemplating whether mainstream is still the right place for her, but it seems my options are limited without an EHCP. I am worried sick about her and her prospects of getting the education she deserves and leading an independent life. I'd welcome advice about applying for an EHCP and also how I can help socially. I feel like I have been sleepwalking while her world falls apart and I don't know what to do
