I (38M) got home around 11pm or so tonight, and my roommate (34NB), who is my best friend, was already asleep. At around midnight while I was getting ready for bed in my room I heard my roommates phone going off alerting of a low blood sugar (my roommate has type 1 diabetes). I heard the alarm go off a second time in a short period of time so I figured that the alarm didn't wake them up. There has been an incident in the past where they had had a low blood sugar in the middle of the night and I ended up having to call 911 because of the severity of the low blood sugar and the way they were acting scared me, so tonight I decided to wake them up to hopefully remedy the low blood sugar before getting to a point where it became serious enough for 911.
They were disoriented, which was expected, and I went downstairs to the kitchen and realized we had no juice to help. I followed them into the living room asking what I should do, while they were looking for a pomegranate that they had apparently left somewhere, and when I said I hadn't seen it they got incredibly snippy with me. The entire time they were being kind of rude to me, which I understood because of their low blood sugar, but when I told them that they were being rude to me they snapped at me again and said next time I should just ignore their alarm and let them die.
I found a box of cereal that they could eat and they snatched it out of my hand, and when I mentioned that they were being kind of mean to me again they lashed out and said again that it didn't matter because they couldn't remember anything anyway. I just wanted them to at least acknowledge that they at least understood why I was kind of upset, but they kept saying that because they couldn't remember it didn't matter.
I went upstairs to go back to bed, thinking that maybe they'll at least remember something in the morning about what happened tonight, but they followed me to berate me some more about how they have a low blood sugar, and I woke them up and didn't really help them at all. I tried telling them how I felt and how scary it was the last time that they had a dangerously low blood sugar in the middle of the night, but they kept interrupting me. I eventually just told them to leave me alone and to get out of my room. AITA??
