My view is..

Why fret? our immunity has made this silly mistake and now we have to deal with it. We can use it as an opportunity to take better control over our lives. We have an immediate counterforce to some of our bad habits. Eat a less sugar (I go super low carb but thats besides the point and not for everyone), exercise more frequently, challenge our minds to find out the right diet, exercise plan and insulin dosage for us as individuals. As with most things, sulking offers quite literally nothing worth value for our control over it. As you said, it could be worse. Before I was diagnosed w/ t1d I lost a boatload of weight and was exceptionally emaciated (among the other symptoms). I looked on the brink of death. I was positive it was cancer or something worse. It wasn't. Perspective.

The first recorded case of these symptoms was 1552 b.c. There were likely cases before this (Modern humans have existed for somewhere around 200k years.) but lets be conservative with our perspective. This first recorded case was 3569 years ago. Insulin was discovered in 1921 by a good fella named Frederick Banting (this man is your patron saint). 1921 was 96 years ago. You were lucky enough to be born in the 2% (but likely much much less) of the time that we actually have a way to control this. If you had been unlucky enough to get this in other 98% you might have died a skinny, depleted, hungry, dry mouthed, bed wetting version of your current self. But you weren't that unlucky. Perspective.

Just play the part of your pancreas for a total of like (?) 15 minutes everyday and get on with it. This isn't going to stop you from doing anything you were going to do before besides, like, eating a cinnabon or something
