I was diagnosed with diabetes in late July. At the time of diagnosis, my blood sugar was at 365 ml and my vision was already very bad (I couldn't make out the features of people who are not standing right in front of me. If I know you, I would know you are the one, but I wouldn't be able to describe your features if asked. My fingers were constantly tingling (A symptom of nerve damage caused by the extreme high blood sugar) and I felt like a total wreck.
I knew I was overweight, but didn't feel it was that bad (I weighed like 90kg, weigh below 80 now). At least I was hardly ever the biggest person in the room. I do drink, but very passively—once in a long while—mostly while hanging out with friends and at most 2 bottles.
I didn't consider myself a candidate for diabetes as I didn't know of a family member that had it. So getting diagnosis that read diabetes was a shock.
