My 16 year old DD isnt diagnosed but to me (and to her) everything points to autism.
She is super high achieving at school, very bright plus intense focus and discipline. Adamant about getting all 9s at GCSE, her mock results were stellar. Particular excellence in music and languages. Contributes well in class apparently. Special interests around marvel and star wars, can talk for a long time on these! She has expressed the feeling that she is 'weird' and doesn't fit in.
Better with friends in the last year or so, currently has one close friend, who she considers her girlfriend but talks about being married to a man in the future and having children. Finds social interaction stressful and difficult, even with her grandparents.
Can't bear unexpected change. I put some temporary curtains up in her room as we'd just moved house. When she came home from school and saw them, she sobbed for half an hour till I took them down.
Lots of sensory issues with food since she was a toddler. Period of anorexia this time last year but we managed to navigate through that and she is at a good weight now. Still a lot of anxiety around food re timings etc. Can be obsessive about exercise, we also watch this.
Year 11 has been better for her and I think she will continue to find her tribe.
