I've experienced all kinds of loss, and it's horrid. There's no way to avoid it, of course, unless you shut yourself away from all humans.
Losses that 'fit the norm,' as it were, are still painful, but, sad to say, kind of expected. I'll take my dad's dad as an example. The poor man was 99 1/2 years old when he died and was pretty miserable, physically. His wish was to avoid 100...and he got his wish. Seriously, at my age, I can't even imagine myself at that age. I'm already crotchety! He wasn't, though. He had a ready laugh and a positive outlook, and I could sure learn a lot from that. Of course, I drive and he didn't near the end, so I'm blaming horrible drivers for my temporary moments of crank.
The other side of the coin is the unexpected loss: The loss that smacks you from out of nowhere and turns you inside out; the loss that has you asking over and over, why, why, why; the loss of the young. Even years later, you'll ask yourself what they would be doing, how they'd look, whether or not they'd have kids, if only...
I lost a cousin and a sister, both too young. Even after more than 20 years, I miss them. I cry and get mad all over again because the world won't have them in it. Both could make me laugh with a single look and/or eyebrow wiggle.
If this post serves you at all, let it be a reminder to stay in touch, tell people how you feel, stop competing for the all-important last word and, lastly, love your peeps.
