Diabetes is currently trying to kill me with a severe headache. So, the most cogent piece of advice I have right now is this; Don’t let diabetes explode your head!
I can also say that doing something distracting, like writing something really stupid in a blog post, can take your mind off the pain and make it easier to survive an exploding head.

Pain in your head can make you surly and mean. See the photo of my headache above? Try not to be as ugly on the outside as you are on the inside if your head is exploding.

If your head is doomed to explode no matter what you do, quickly search your memory for every cute girl you were ever fond of and quickly remember each and every cutie’s face. Try to scroll past any blue fauns in your memory. No good comes from that if your head is about to explode. That’s a complicated metaphor and likely somewhat sexual in an inappropriate way.

And don’t worry about becoming a ghost after your head explodes. Ghosts are not real. And you won’t have any worries after your head explodes because an exploded head can’t do any thinking, and worrying… especially worrying too much… is a waste of time because it is a form of thinking an exploded brain can no longer do.
That’s all I have to say about wisdom today… After all, I have a really bad headache.
