so I have a friend who (about a week ago) was visibly not feeling well. They missed about 4 days of school. When they got back, they randomly made a comment about being in the hospital, and on and off comments about their "blood sugar being low". Another friend of mine also saw them at the nurses office (this person is almost never sick). Is it possible my friend has been diagnosed with diabetes and has not told me? If so, what should I do?
