My first sign is feeling anxious, trying to finish quickly the job I’m doing, this is probably due to an increase of Adrenalin. This then mixed with getting hotter, then noticing slight changes in focus. I don’t always feel hungry.
Post stress for me. Dad died, pressure at work, long hours, long drives then bam Type 1 taking insulin. Came on very quickly. My opinion is that stress makes you more susceptible to the virus that causes an autoimmune affect on pancreas.
