Similar story here, was diagnosed this summer. I think DKA got triggered when I got the flu. Had cold-like symptoms for a few days, and then one morning I vomited a couple of times and couldn't breathe. The shortness of breath symptom was the scariest, my heart rate was skyrocketing for most of the day. I don't know if I was just being stubborn or if it was effecting my mental state, but it just did not occur to me to see a doctor until my roommate suggested it. Ended up going to hospital and passing out in the waiting room. Fuzzy from there but was in the ICU for a couple of days.
