Thanks Juturna, Cheryl, Ohev & moon_beam. Your words & commiseration are much appreciated.
I'm pretty sure I'll survive this & learn to love another pooch eventually, but what's alarming is how much it hurts more each time. It's like a wound that becomes a scar, and then you get cut in the same spot again. And again. It gets worse & worse, uglier & uglier, more & more sensitive, until I suppose eventually you're completely mutilated.
That's probably a lousy &%^ogy, but it's the only one I could think of.
I agree with Cheryl that a "rebound" adoption rarely, if ever, fills the void. But one thing it does do is that it creates a distraction. My girl was an abused dog whom I rescued 10 years ago. The very day she died--that same morning--I was back at the local animal control rescuing other dogs who were about to be put down.
2 of them are at my feet right now. There are 3 others I found homes for. Are 5 lives equal to the price of the 1 that I lost? Not even close. How about if I save 50? 500? Like you said, Juturna, no other dog or dogs will replace her. But this serves as a distraction, and I'll keep doing it because it helps me sleep at night. Whether or not this is a true cure or just a "drug" I don't know. I guess I'll find out if I crash.
Ideally I'd forget about dogs completely, go party on the Riviera & a few years later this will all be a forgotten nightmare. But will that accomplish anything for the world? Maybe I'm an idiotic masochist, but I feel like I have to dive right back into saving dogs, otherwise her death would be completely meaningless. The problem is that I know it's going to keep hurting more & more.
Jeez well thanks for listening to my meanderings. I don't know if any of it makes sense (none of it makes sense to me). I wish I could post a picture of my girl, but I can't bring myself to look at those pics. And I don't think they'd do her any justice anyway.
Years ago, I stumbled on a news photo of a man whose house had burned down and who lost everything but his dog. That photo pretty much summarizes how I felt about my girl every single day...

Thanks again for all your support, everyone. I sincerely hope you each find your respective "cures", whatever those may be.
