Don't worry, I'm sure it will pass.
So many of my friends and family are going through rough times right now; family strife, all sorts of kid problems (and lack of kid problems), terminal illness, you name it. I wish I had a jet plane so I could fly around hugging everyone who needs it. But the only tiny bit of comfort I have to offer is this.
You don't grow emotionally, learn compassion, kindness, or otherwise become a good person, when your life goes smoothly. You learn those things when all hell is breaking loose in your life, and you realize just how bad things can suck, and after that, you can look at the situations of other people and maybe eke out a little kindness you didn't have before. (I have been told I am kind. I'm not sure I am, but if so, it's because life beat it into me.) That's a good thing. Though my reaction to rough times these days is often "Oh great. Another goddamn life lesson. I should be fucking enlightened by now."
Swearing also helps, I find. And throwing dishes. But the dish-throwing can get expensive.
Every time I think I've made peace with issues in my life, the universe seems to turn around and take a bite out of my ass just for the fun of it. Raising the Goob is in some ways horribly difficult because it makes me miss my mother so much, and rakes up old issues with my father that really are unsolvable. Maybe that's the goddamn life lesson I get with this round; acceptance.
And so we age, and we live through the rough times, and learn to value the good times all the more, and maybe edge a tiny little baby step closer to nirvana/fulfillment/enlightenment/heaven/peace/knitting everything out of silk.
Everybody together now. Repeat after me. "Oh goodie. Another goddamn life lesson." Hugs and hard cider, all around.
