My best friend from childhood....I'm talking almost 30 years of friendship....died suddenly last January at the age of 41. He was pretty healthy looking, though he was a Type 1 (childhood) diabetic and had been on insulin almost all the time I'd known him. He had sudden cardiac arrest while driving his car to work, after leaving the gym in the morning, where he had just worked out. Left 2 teenage kids behind. This has greatly affected me the last year since we were so connected. I keep thinking that since he's dead, my death is right around the corner, especially being diabetic myself (though mine is adult onset, Type 2, but I'm on insulin for it). I literally live my life thinking about death all the time. I don't think that would be the case if he had died in a car accident, or by some other accident, but because it's health-related, and was so sudden, I can't help but obsess over it and feel doomed.
