My mom had worried and worried for a lot of things about me when I left her for college at 18. I lived in school dormitory with 9 other girls and learned to do things on my own since. I had plenty of bad experiences, also learned plenty good ones from other girls. Right now I am half-of-the-earth away from my parent, living my own life, happily.
What I mean to say to OP is that please don't worry too much about your daughter. There are plenty of moments in life that we have to learn by ourselves alone, no one else can really help us. I know it broke my mom's heart to hear about I had food poisoning here or I felt there.
And yes, I was "that" girl - odd one, smart but needs very rigorous schedule for everything, from eating, sleeping, brushing teeth, playing time, etc.. My girls in the dormitory had helped me tremendously. I actually gained weight during living in dormitory. It made my mom raised her hands up to the air and said "I wish I had sent you to school a long time ago!" There was one time she said she wished I were a draw so she could just open the draw, dump a bowl of food in there, close it and be done with meal time
Wish you and your girl good luck and all the best!
