DD16 thinks she has ADHD (based on online quizzes, which I take with a pinch of salt!). No concerns have been raised by her school but her elder sister is currently being assessed for ASD which was also completely missed by school so I don't have a lot of faith in that process.
DD does well at school (all A/A star at GCSE) and doesn't seem to have social issues or special interests so I don't think she has ASD. However she is incredibly disorganised and messy at home (seems to cope with school though), has a very short fuse (but recovers quickly), has a lot of trouble sleeping/switching off, has a lot of sensory issues, has an incredibly restricted diet (goes beyond "fussy" and she genuinely can't eat a lot of stuff), her handwriting is almost illegible, she can focus but also daydreams a lot, she needs a lot of down time and she has been assessed with slow processing. She also lacks confidence in her abilities and is very fidgety. She is very impulsive and struggles to save money etc.
She is fairly popular at school (with students and teachers) and doesn't have any behavioural issues.
It's so hard to know how much of this is typical teenager and what might be potential ND. I realise the internet can't diagnose for me but I'd love to hear people's views so I don't make a fool of myself raising it again with her school.
What is the best way to start an assessment process? Via the GP or school?
