Sorry to hear big guy. I know it probably won't help, but I got a story for you.
My sis, who is 7 years older than me was in a car accident when she was 19. Been a paraplegic ever since...34 years now. Anyways, right after she got out of the hospital, she bought a German Shepherd. Gorgeous dog. She raised him as a puppy. His name was Rocky. Her and that dog was SOOOOOOO close. Think about it...you think you're close to a dog now...imagine how MUCH closer you would be if you are in a wheelchair and you're with that dog always. He was her best friend.
Fast forward 4 years. Rockys grown, and a monster. Biggest Shepherd I ever seen...he weighed 155. Great dog. Anyone ever even LOOKED at my sis the wrong way, he was ready to rip 'em up. Well, she had a party...it was summer time...July and hot. She had a house way out in the country...alot of land and privacy there...great partys we had there. We was all outside around the bondfire having a good ol time. I think we ended up crashing around like 4am or 5am. Wasnt that many people there...only close freinds...perhaps maybe 8-10 people this time. Sooo, come next day, me, my gf and my sis and a few others all wake up around 1PM. She calls out for Rocky, as she just put dog food in his bowl. He doesnt come. Keeps calling him...nada. So me and my friends go outside to look for him...calling and calling...Rockys nowhere to be found. Sooo, we just figure he took off chasing a rabbit or something like he has done a million times before and will be back.
Well, after a couple hours, one of my friends is ready to roll, so he heads on. Next thing we all know, he is screaming outside. WTF? I run outside, and in his car, is Rocky..dead. Suffocated from the heat. Claw marks and teeth marks all over the inside of the doors and windows of the car. Apparently, the night before, someone went to my friends car to grab a beer or smokes and Rocky jumped in the car and they didnt know it when they closed the door shut. When it initally happened, my sis and me was ready to KILL a mofo! But after time and our senses kicked in, we realized it was nobodys fault per se, as we were ALL drunk as a mofo. And that was an unfortunate, easy accident to happen to anyone. Everybody there loved my sis and Rocky too. It was an accident, HOWEVER, that didnt help matters any. He was gone. And my sis LOST IT. It killed her inside. OMG it killed ME, so I cant even imagine how hard it hit HER. It took her a longggggggggg time to come around after that.
Again, I know this don't help you bro, but I guess my point IS, it indeed could have been much worse. I am sorry and hope you can get over it in time my man.
