My mum had all sorts of bizarre ideas about me as a teen, and now 
She thought I was going to struggle with things I had no issue with, made all sorts of wrong assumptions about friends, family and what I should do a uni. With the best will in the world her active job was over by the time I was going to uni, I got money, food and love still for a few years but my choices and mistakes were mine not hers. I had a good time, I drank far to much, slept with unsuitable boys, took drugs the works. None of mums business what I did as i was an adult. Working stuff out by trying things.
I made good friends at university but not life long ones. I met my dh at uni but I hated him then. Not now of course
I expect to be making similar ridiculous statements and having similar concerns about ds in the future. Very bright, no friends and very belligerent (also has aspergers) so I will probably be very worried about him getting into any university. But it will be up to him, to make his mistakes and learn.
Your dd will make her choices and some of her choices will be made for her. She may well go to an oxford college and hate it. Or love it or just get on with it. I don't know her I don't know you. But at 17 your dd is still working out who she is and your worries have nowt to-do with it. It is your burden, don't give it to her. Hope it all works out.
