@mollie1 As a college student with a similar story of being diagnosed at 15, I can understand. I am glad to hear that he continues to do well in school and with his A1c. I am 18 (almost 19) and in my freshman year. I asked for things like snacks, the ability to ask for extended test time (if sick or low/high bg), having water in class, excused for the bathroom anytime. The big one for me was early registration so that I could make my schedule around mealtimes because if not, I would have been scheduled for some classes during lunch hours (although I am at home this semester). My college told me that I would have to request an extended time for test with each individual teacher depending on if I need it. It depends on the school, but my school keeps everything private about condition except for what we need accommodations for.
Any other questions or want to chat more about it, let me know.
