It was my fault. . .
I was holding her and I fell asleep. I suffocated her without even knowing. And not only did I have to wake up to my dead beloved pet, I also have to now live with the guilt of having been the one to kill her. She was just a baby. She had never bitten me. She had literally never hurt a living creature. I'd always fed her frozen/thawed. She didn't deserve to die. Nothing in my life was harder than having to bury her.
Thanks for letting me vent.
